Usage

Description

DIISOBUTYLENE, also known as 2,2-dimethylbutene, is an alkene with the chemical formula C8H16. It is a clear colorless liquid with a petroleum-like odor. DIISOBUTYLENE has a flash point of 10°F, is less dense than water, and is insoluble in water. Its vapors are heavier than air. This chemical is primarily used in the manufacture of other chemicals and has potential applications in various industries.

Uses

Used in Alternative Diesel Fuel Industry:
DIISOBUTYLENE is used as an alternative diesel fuel for its potential to be composed into a more sustainable and efficient fuel source. As fuel in single-cylinder engines, it has been reported that the exhaust generated from combustion due to the burning of DIISOBUTYLENE contains high concentrations of olefins, which can be further studied for their impact on emissions and environmental concerns.
Used in Chemical Synthesis:
DIISOBUTYLENE is used as a starting material for the preparation of monoand dialkylated diphenylamines. These compounds are essential in various chemical applications, including the production of antioxidants, rubber additives, and other specialty chemicals.
Used in Manufacturing Other Chemicals:
DIISOBUTYLENE serves as a key component in the production of various chemicals, such as butyl rubber, which is widely used in the tire and automotive industries. Its versatility as a chemical intermediate makes it valuable in the chemical manufacturing sector.
