What is the reaction of vegetable oil with white sugar?
The current reference did not mention what chemical reaction would occur when vegetable oil was mixed with sugar. In practical applications, there was the practice of adding vegetable oil to the pesticide, and there was also the practice of adding white sugar to the Bordeaux mixture to prevent settling, but the reaction after the two were mixed was not involved. There was the practice of pouring edible oil into white sugar and mixing it evenly to apply it on the heel to prevent cracking and peeling. This was just a physical mixture to make use of their respective characteristics. There was no indication of any special reaction. Therefore, based on the available information, it was impossible to determine what kind of reaction would occur when vegetable oil was mixed with white sugar. Read more exciting novels for free
Reaction of vegetable oil and hot naoh solution
The reaction of vegetable oil with a hot solution of soda ash (NaOx) would result in a soap reaction. Plant oil contains fatty acid components, such as Cis- 9 -octadecene acid (CH3 (CH2) 7CH = CH(CH2) 7COON), which react with NaOx. The chemical equation is CH3 (CH2) 7CH = CH(CH2) 7COON + NaOx = CH3 (CH2) 7CH = CH2) 7COONa +H2O. The phenomenon was that the oily substance on the top layer dissolved and turned from an cream to a clear solution. In the production of handmade soap, it was the use of 98% purity of the reaction of the raw materials such as soda and vegetable oil. During the reaction process, it would also produce "vegetable glycerine" with mild moisture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
White sugar water plus soda reaction
White sugar water and baking soda would react. When the mixture of white sugar water and baking soda was heated, the baking soda's component, NaHCO2, would produce carbon dioxide (CO2) when heated, causing a large number of bubbles to appear in the mixture. For example, when making some food, this phenomenon would occur when white sugar, water, and baking soda were mixed and heated according to a certain ratio. Furthermore, the white sugar water and baking soda also had the effect of repelling mosquitoes. The white sugar water was responsible for attracting mosquitoes, and its surface tension could attract mosquitoes. The baking soda was basic, so even if it could not kill mosquitoes, it could make them lose their reproductive ability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The price of vegetable oil
The price of vegetable oil varied under different promotions. In the supermarket, when 88VIP bought 5L of first-grade vegetable oil, the order was immediately reduced by 29.6 yuan, and the VIP88 member paid 57.3 yuan after another 9.5% discount. In the joint activities of Tik Tok Supermarket and Dao Dao Quan, the price of 5L of fragrant vegetable oil was much cheaper than the normal price of the supermarket (70 to 80 yuan), but the specific price was not specified, only emphasizing that the price was very cost-effective.

Price trend of vegetable oil
The price trend of vegetable oil was more complicated. In the early stage, due to the negative factors at home and abroad, its price continued to decline. As of 10:00 on November 5, the average price of domestically imported third-grade rape seed oil was 9674 yuan/ton, down 1.02% from the previous day; At 10:00 on November 6, the average price of domestically imported third-grade rape seed oil was 9550 yuan/ton, down 0.25% from the previous day. Moreover, there were many uncertain factors in the international market. The domestic downstream market had a strong wait-and-see atmosphere, and the shipping speed of oil plants was slow. It was expected that there would still be some room for decline in the short term. However, according to the situation on November 8, the main price of rape seed oil rose by 2.70% to 9816.00 yuan/ton. On the whole, the price of vegetable oil in the early stage was declining due to various factors, but it had risen recently. "The Island of Life" is also a wonderful novel.

Market price of vegetable oil
The market price of vegetable oil varied greatly due to many factors. For example, at 10:00 on November 6, the average price of domestically imported third-grade rape seed oil was 9550 yuan/ton, the benchmark price of rape seed oil on November 7 was 9,466.67 yuan/ton, and the average price of domestically imported third-grade rape seed oil on November 8 was 9924 yuan/ton. In addition, in the retail market, the price fluctuation range is wider. There are 7.5 yuan/catty, 12 yuan/catty, 13 yuan/catty, 15 yuan/catty, 28.5 yuan/liter, 29 yuan/liter, 30 yuan/bottle, 68 yuan/barrel and other different prices of vegetable oil on sale. These price differences are related to the origin of the vegetable oil, whether it is genetically modified, crushing technology, sales channels and other factors.

Price chart of vegetable oil
The price trend of vegetable oil was more complicated and fluctuated frequently. At 10:00 on July 29, the international oil and fat prices fell. The average price of domestic imported grade 3 rape seed oil was 8616 yuan/ton, down 2.85% from last Friday. At that time, the domestic downstream market was in a wait-and-see atmosphere, and the oil factory was slow to ship. It was expected that the price would continue to fall in the short term. At 10:00 on October 31, despite the increase in favorable factors in the international market, the price of imported rape seed oil was lowered due to the decline in the price of canola seeds in Canada and the low demand for rape seed oil in the domestic downstream. The average price of domestic imported tertiary rape seed oil was 9564 yuan/ton, down 0.21% from yesterday. However, the palm oil market was strong, and favorable factors still existed in the international market. It was expected that the price of imported rape seed oil would rise in the later period. On November 6, the futures price of rape seed oil weakened sharply. The market expected that the import supply of cuisine in the later period would increase significantly. In the fourth quarter, the domestic rape seed import volume was sufficient, the inventory continued to grow, and the spot pressure caused the futures to weaken. On November 8th, the main price of vegetable oil rose by 2.70% to 9,816.00 yuan/ton. "The Island of Life" is also a wonderful novel. Everyone is welcome to read it!

Does vegetable oil react with plastic?
From a chemical point of view, plasticizers are more easily dissolved in oil-based substances. For example, edible oil packaged in plastic bottles may have a higher risk of migration of plasticizers, indicating that there is an interaction between vegetable oil and plastic. In addition, the main component of the plastic bag, namely the colloid, was more oleophile, and the oil would penetrate through the gap between the film's molecular chain and the chain segment. This also indicated that there was a certain interaction between vegetable oil and plastic, but this was not necessarily a chemical reaction. At present, there is no evidence that vegetable oil and plastic will undergo a chemical reaction to produce new substances, but there may be phenomena such as migration of substances when the two come into contact. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reaction between the kerosene and the oil
At present, the proportion of crude oil in China's graphene production capacity is more than half. From 2019 to 2023, the dependence of international crude oil on graphene is 30% - 79%. In 2023, the dependence is 55%, which is 24% lower than that in 2022. The price trend of graphene is the same as that of crude oil most of the time, but sometimes there are differences. From the chemical structure point of view, there was no mention of the direct reaction between the oil and the graphene. It was only mentioned that due to the existence of the side methyls in the graphene, tertiary carbon atoms appeared on the molecular chain. The tertiary carbon atoms were easy to undergo an oxidization reaction when they came into contact with copper ions, resulting in poor oxygen resistance and radiation resistance of the graphene. There was no data to show that it had a specific reaction with the oil. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
