The toluene diisocyanate has 2,4-toluene diisocyanates and 2,6-toluene diisocyanate (TDI).

There are two isomers of 2,4-toluene diisocyanate and 2,6-toluene diisocyanate (TDI). According to the content of the two isomers, there are three standard products in the industry: (1) TDI-65 contains 2,4-TDI65%, 2,6-TDI35%; (2) TDI-80 contains 2,4- TDI80%, 2,6-TDI20%, more common; (3) TDI-100 contains 2,4-TDI100%. Carbon dioxide occurs with water effect. Easy to work with compounds containing active hydrogen atoms. Linear polyurethane or polyurethane resin with diol effect.

mercaptan wrapped in fuel is malodorous and corrosive, which reduces the lead content of gas. except, mercaptan is also an oxidation initiator, which can promote the oxidation and condensation of risky components in fuel to gel, resulting in terrible garage balance of gasoline. cobalt phthalocyanine sulfonate is an powerful catalyst for disposing of mercaptan sulfur from heavy oil, and it has the identical effect. whilst in use, dissolve the catalyst in 10% alkali solution, heat it slightly for a time frame, and stir to dissolve it before use.

Ammonia, also known as Amonia water, can be written as NH3(aq), which is an aqueous solution of ammonia, colorless, transparent and has a pungent odor.

Only a small part of ammonia molecules react with water to form ammonia monohydrate, which is a weak base that only exists in ammonia.

Industrial ammonia is an aqueous solution containing 25% to 28% ammonia. Only a small part of ammonia molecules react with water to form ammonia monohydrate, which is a weak base that only exists in ammonia.
