Trigonox AW70 - Introduction:
tert-butyl hydrogen peroxide (Tert-butyl Hydroperoxide), referred to as TBHP, is one of the most commonly used alkyl hydroperoxide.
Commodities are generally light yellow transparent non-volatile liquids, slightly soluble in water, miscible with organic solvents.
Butyl hydrogen peroxide is mainly used as an initiator for free radical reactions or polymerization reactions in industry.
Compared with the decomposition products of most other initiators, it is acidic.
The decomposition products of TBHP are tert-butanol (TBA) and a small amount of acetone, which are not corrosive to the equipment, so the requirements for the equipment are not high.
The decomposition activation energy of O-O bond in tert-butyl hydrogen peroxide is low, which can be used as an improver to improve the decane number of diesel oil.
Tt-butyl hydrogen peroxide is a very important organic synthesis intermediate.
Trigonox A-W70 is a crosslinking agent used in unsaturated polyester crosslinking under medium and high temperature conditions.
Under the action of the metal catalyst, TBHP can also be used as an oxygen supplier to selectively oxidize unsaturated hydrocarbons such as acetals, allyl alcohol compounds, and unsaturated hydrocarbons.

colorless transparent or yellow liquid. Melting point -8 ℃, boiling point 35 ℃(2.66kPa),40 ℃(3.06kPa), relative density (20/4 ℃)0.896, refractive index 1.4007.
Trigonox A-W70 can be miscible with organic solvents such as ethanol and ether.
The solubility in water is 12g, which is weakly acidic.
Trigonox A-W70 is stable below 75 ℃, loses oxygen at 90~100 ℃, and explodes at 250 ℃.
Trigonox AW70 - Use:
Trigonox A-W70 is used as a catalyst for polymerization reactions.
Trigonox A-W70 is used as an introducer of peroxide groups in the substituent reaction.
Trigonox A-W70 is a first-class organic oxidant, which is easy to explode at high temperatures.
Trigonox A-W70 is used for dyeing and printing cotton, viscose, silk, cotton fiber and other fibers and their fabrics, and also for dyeing polyester/viscose blended fabrics.
Trigonox A-W70 can be used alone or for color matching.
