【Chemical formula】
【Nature】 White or reddish-brown crystalline powder, with a very special fragrance pale, almost insoluble in water (about 5%), soluble in ethanol, ethyl acetate, ethyl ether and other organic solvents.
Boiling point 295℃, melting point 126.5~128.5℃. Has against putrescence to the majority fat, particularly vegetable oil. Case of iron, copper does not change color, but if there is can be converted to a pink base. Can effectively inhibit Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Bacillus and other bacteria producing shortness of breath, as well as black Aspergillus, Aspergillus versicolor, Aspergillus flavus and other microbial growth.
【Main purpose】 MTBHQ(single tertiary hydrogen wake) is a light brown solid, which is mainly used as polymerization inhibitors and industrial antioxidants .It’s more useful in many application than the hydrogen wake due to the high solubility at higher temperatures .What’s more, blocked hydroxyl also makes MTBHQ as an important organic intermediate .
