Application
Tert dodecyl mercaptan is a polymerization regulator of synthetic rubber, synthetic resin and synthetic fiber, especially commonly used in the manufacture of styrene-butadiene rubber and ABS resin, which can reduce the branching degree of the polymer chain and make the molecular weight distribution uniform, often used as a nonionic surfactant and an intermediate in organic synthesis. Used in the manufacture of fungicides, insecticides, rust inhibitors, lubricating oil additives, drugs, etc. It can also be used as “gold water” in the ceramic industry and an acidifier for oil wells.
tert-Dodecanathurol (25103-58-6) is an intermediate in organic synthesis, used to manufacture drugs, pesticides, fungicides, rust inhibitors, lubricant additives, etc., and can also be used as “gold water” in the ceramic industry. It is a relative molecular mass adjuster for the polymerization of synthetic rubber, synthetic resin, and synthetic fiber, especially in the synthesis of styrene-butadiene rubber and ABS resin by emulsion polymerization, which can reduce the branching degree of polymer molecular chains and make the relative molecular mass distribution uniform.
It is the best relative molecular mass regulator and chain transfer agent in polymerization processes such as styrene-butadiene rubber, nitrile rubber, and synthetic resin.
Storage
It has strong reducibility, wear labor protection when using, and operates in a fume hood. During storage, leakage must be strictly prohibited, stored in a cool, dry, well-ventilated non-combustible material structure warehouse, and a small number of products can be stored at low temperatures. Keep away from heat and open flames, especially direct sunlight. Isolated storage and transportation with oxidants, combustibles and strong acids.
Tert dodecyl mercaptan is Class 9 Dangerous Goods, dangerous package available, land and sea transportation workable.
