A detailed explanation of the main synthesis methods and uses of isobutane:  

Isobutane is a high quality chemical material, has gradually been widely used, for the main synthesis method of isobutane, how much do you know, let's understand in detail:  

1. It exists in LPG, natural gas and cracked gas.  It is obtained from the carbon fourth fraction produced during petroleum cracking by separation.  

2. Using industrial isobutane as raw material (82% ~ 91%), a three-stage adsorption process was adopted.  The first level adsorber removes C2, C3, butane and 1-butene and other impurities, the second level adsorber removes isobutene, in the third level adsorber further removes C2, C3 hydrocarbon impurities, the product purity is greater than 99.99%.  

Description of isobutane's main uses:  

1. High purity isobutane is mainly used as standard gas and special standard mixture.  

2 used for the synthesis of isooctane, as a gasoline octane number improer, used for making isobutene, propylene, methacrylic acid, used as a refrigerant, etc.  

3. Used for alkylation with isobutene to make isooctane, as octane number improer of gasoline.  Isobutylene and propylene can be prepared by cracking.  Alkylated gasoline can be prepared by alkylation with isobutylene and propylene.  Methacrylic acid, acetone and methanol can be prepared.  Can also be used as a refrigerant.  

The main synthesis method and main use of isobutane is these, I believe you have been able to understand, we must follow the instructions to carry out the correct operation, so as to obtain a higher operating effect.
