Product Application

1. It is mainly used for the alkylation reaction with isobutylene to produce isooctane, and serves as an octane number improver for gasoline. It can be cracked to produce isobutylene and propylene. Alkylation with n-butene and propylene can produce alkylated gasoline. It can also be used to synthesize methacrylic acid, acetone, methanol and other products, and applied as a refrigerant.

2. High-purity isobutane is mainly used as standard gas and for the preparation of special standard mixed gas.

3. It is used to synthesize isooctane as a gasoline octane improver, and for the production of isobutylene, propylene and methacrylic acid, as well as being used as a refrigerant.
