n-Butane reacting to i-Butanen-Butane can be converted to i-Butane through an crystallisation reaction. For example, in the crystallizer, after the feed of the Butane is separated from the IsoButanizer, the bottom of the tower is mainly n-Butane, which is mixed with hydrogen and then heated to enter the reactor.(The reaction pressure is about 2.1 - 2.8MP, the temperature is 145 - 205 ° C, the mole ratio of hydrogen to hydrogen is 0.1 - 0.5, and the space velocity is 3 - 5h ¹). The reaction product is separated into hydrogen (recycled) by the splitter, and then a small amount of cracking gas (used as fuel gas) is separated by the stabilizing tower, and then it is sent to the de-iobutane tower. The n-Butane at the bottom of the tower can be recycled for reaction and converted into i-Butane.

Substitution Reaction of Butane and Bromine SteamButane and Bromine vapor would undergo a substitution reaction under light conditions. During the reaction, the hydrogen atoms in the Butane molecules would gradually be replaced by Bromine atoms, forming a variety of Bromobutane products. For example, n-Butane produced various kinds of chloride-Butane through free radical substitution reaction. The reaction between Butane and Bromine vapor was similar. During the reaction, similar free radical would participate in the reaction, gradually forming products such as monobromobutane and producing Brr.

Reaction equation of n-Butane and Cl2The reaction equation between n-Butane and Cl2 was: CH3CH2CH2CH3 + Cl2 = Illumination = CH3CH2ClCl
Since n-Butane is C4H10, there are 10 kinds of chloride-substituted products. N-Butane was simplified as C-C-C-C, numbered 1, 2, 3, and 4 from left to right. There were two kinds of compounds, one at position 1 and the other at position 2. The reaction of n-Butane and Cl2 may also produce other chloride-substituted products, such as polychloride-substituted products. The reaction process is more complicated and will vary with the reaction conditions and the amount of Cl2.

The reaction process of the formation of Butane from etheneThe following is the reaction process of several kinds of ethene to produce butan:
1. First, the reaction of ethene (CH Chi =CH Chi) with Bromine (Br Chi) produces 1,2 -dibromoethane (CH Chi Br-CH Chi Br). 1,2 -dibromoethane will undergo an elimination reaction under the effect of a strong base alcohol solution to produce ethyne (C Chi H Chi). The addition of ethyne itself (under the effect of a catalyst) will produce ethenylyne (CH Chi = CH-CH Chi Chi). The reaction of ethenylyne with sufficient hydrogen will produce butan.
2. After the decomposition reaction, it was possible to produce CH CH (CH CH), which was then converted to CH CH(CH)CH CH (CH) CH CH, which was then converted to CH.
3. The reaction of ethene with hydrogen bromides to form dibromoethane, the elimination of dibromoethane to form ethyne, the reaction of ethyne with Na to form ethyne, the addition of ethene with hydrogen bromides to form ethyne, the reaction of ethyne with ethyne to form 1 -butyne, and the hydrogen addition of ethyne to 1 -butyne to form butane.

liquid fuelLiquid fuel was a large type of fuel. It was a liquid flammable substance that could generate heat or kinetic energy, mainly containing a mixture of carbon and hydrogen. Natural liquid fuel included oil or crude oil, processed gasoline, kerosene, diesel, fuel oil, etc., which were obtained from oil processing, and the oil obtained from the dry refinery of oil shales, as well as artificial oil synthesized from carbon dioxide and hydrogen. The alcohol-based liquid fuel was mainly made of a mixture of alcohol and alcohol. Alcohol was a colorless, transparent, volatile, flammable, and slightly mellow toxic liquid. Most alcohol-based liquid fuel was mainly made of alcohol, but there were also cases where a small amount of industrial alcohol was added. The water-based fuel was made of various chemicals and processed under the effect of a catalyst. It was a clean fuel without black smoke, odor, and harmful substances when burned. It could be used in the fields of restaurants, industrial furnaces, and so on. There was also the liquid fuel used for the side furnace. It was an environmental friendly oil specially used for copper pots. It was a safe mineral oil fuel that could not be ignited by open fire. It was colorless, odorless, and not pungent or eye-piercing. On the military side, the common liquid fuel for intercontinental missiles was nitrogen tetrode and unsymmetrical dimethyllane. Some scientists also believed that liquid oxygen and liquid hydrogen were the best oxidisers and combustion agents.

SpaceX fuelThe fuel of the SpaceX rocket was as follows: The white vortex formed during the launch of the SpaceX rocket was related to fuel. The super-heavy thrusters and the final stage of the interstellar spacecraft were made of steel. When the fuel tank was filled with fuel, the amount of propellant would appear in the form of frost on the outside. This was a key indicator of the preparation work before flight. The first-generation interstellar spacecraft had a propellent capacity of 1200 tons, and the second-generation interstellar spacecraft's final tank was filled with more propellants than the first-generation spacecraft. After analysis, the newer spacecraft might be able to carry 1.5 times more propellants than the previous generation spacecraft. In addition, SpaceX may drill natural gas in Texas as a power fuel to launch its new Starship.
