| Hazard Information | Back Directory | [Description]
Diphenylsilanediol is a chemical compound that is used as a catalyst. It can be produced by the reaction of diphenylsilane with sulfuric acid. This chemical has been shown to have high thermal and chemical stability, making it an ideal material for catalytic materials. Diphenylsilanediol has also been shown to be an efficient solid catalyst for synthesizing hydrocarbons from hydrogen fluoride and hydrochloric acid. The efficiency of this catalyst may be due to its ability to reduce the activation energy required for the reaction. Diphenylsilanediol is an important material used to manufacture silicone resins and rubbers. In addition, it is helpful as an additive for organopolysiloxanes that are convertible to the cured solid.
