The most commonly used polymerization process uses methyl chloride as the reaction diluent and boiling liquid ethylene to remove the heat of reaction and maintain the low temperature needed. The final molecular weight of the butyl rubber is determined primarily by controlling the initiation and chain transfer reaction rates.

- What is rubber antioxidant TMQ TDQ Rd?
- Rubber Antioxidant TMQ, TQ, TDQ, RD: It is a very important category of rubber antioxidants. It has a good powerful effect on heat, oxygen, and fatigue aging.
- What is TMQ used for?
- This antioxidant has a strong inhibitory effect against the oxidation of metal catalysts. TMQ is widely used in the manufacture of motorcycles, bicycle, rubber, plastic, adhesive tape, wires, cables, and other rubber products. This antioxidant can be used as a stabilizer for isoprene rubber, polybutadiene rubber, and styrene-butadiene rubber.
- What is TMQ antioxidant?
- Shanghai Chemex is one of the most reputable suppliers of this chemical in the world. TMQ Antioxidant is a low molecular weight polymer that appears brown or amber. It is soluble in benzene, acetone, and other organic solvents but insoluble in water. It is slightly soluble in petroleum hydrocarbons. It has low toxicity and pollution.
- Is TMQ antioxidant combustible?
- TMQ Antioxidant is a low molecular weight polymer that appears brown or amber. It is soluble in benzene, acetone, and other organic solvents but insoluble in water. It is slightly soluble in petroleum hydrocarbons. It has low toxicity and pollution. You should note that this product is combustible.
- How does TMQ synthesis work?
- The catalytic synthesis process of TMQ: Aniline and acetone antioxidants are considered raw materials, it also uses an acidic resin as a catalyst. First once add aniline, part acetone in the reactor, Then add the acid resin and stir, and stop heating when the reactor is heated to 90-94.9 ℃ of temperature.
- How long does TMQ reaction take?
- The reaction temperature remains constant at 70 to 80 ° C and the reaction mixture is stirred continuously for 30 minutes. After one hour, aniline is detailed at normal pressure at 28 to 60 ° C to produce TMQ antioxidants.
