1,1,3,3-Tetramethyldisiloxane Chemical Properties,Uses,Production

Description

1,1,3,3-Tetramethyldisiloxane is soluble in many organic solvents, such as aromatic hydrocarbon and petroleum hydrocarbons, and so on. This product is a kind of widely used organic silicon intermediates, and usually be used as organic silicon blocking agent. Due to containing reactive Si-H groups in the molecular structure, it can be used in the synthesis of copolymer macromolecule by hydrosilylation. The synthesis of copolymer macromolecule can be made into a series of reactive silicone oil.

Chemical Properties

Colorless or yellowish transparent liquid

Uses

1, 1, 3, 3-Tetramethyldisiloxane is a kind of siloxane derivative, and can be used as a monomer for the preparation of silicone polymers or silicone resins. It is used as an intermediate for preparing other organosilicon compounds. It is also used in non-aqueous polymer preparation as well as a laboratory reagent. In organic synthesis, it finds an application as an effective reducing agent in platinum-catalyzed reduction of carboxamides to amines as well as in the Au/TiO2-catalyzed hydrosilylation of carbonyl compounds (e.g., reduction of aldehydes or ketones) relative to monohydrosilanes. It can also enable a direct bromination of carboxylic acids in the presence of indium bromide (InBr3) as catalyst.

Uses

1. Synthesis of polysiloxane containing faculties end groups.
2. Can be used for the preparation of high performance organic silicone surfactants.
3. Applicable to the production of many products, such as addition silicon rubber, silica gel, Hydrogenpolysiloxane and plastic, resin modifier, dendrite polymer special additives, etc.
