tert-Butylhydroquinone(TBHQ) CAS1948-33-0 TBHQ Mainly used as inhibiter for polyvinyl chloride. In food industry it is used as antioxidation for vegetable oil and fat, roasted food, fried food and meat products. It also used as stabilizer for insecticide, as well as intermediate for dye and pharmaceutical. Tertiary Butyl Hydroquinone (TBHQ) is the synthetic food grade antioxidant, used in stabilizing various vegetable oils, fats and food against oxidative deterioration, thus retarding development of rancidity in these products and extending their storage life.

Methyl tert-butyl ether (MTBE) is a colorless, transparent, low-viscosity, volatile liquid with a distinctive odor and an oxygen content of 18.2%. lts vapor is heavier than air. Diffuses along the ground and burns when co-existing with strong oxidants. The main use of methyl tert-butyl ether is as an organic solvent and can also be used as a gasoline additive to make it more antiknock. Application ethyl tert-butyl ether (MTBE) is mainly used as gasoline additive, has excellent knock resistance, improves octane number, and can also be cracked to produce isobutene has good miscibility with gasoline, less water absorption, no pollution to the environment, can be improved as an analytical solvent, extractant, in chromatography especially high pressure liquid chromatography as a removal agent, and some polar solvents such as water, methanol, ethanol and other azeotrope formation. Mtbe also has a mild narcotic effect.
