1,1,3,3-테트라메틸디실록산 C화학적 특성, 용도, 생산
개요
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.화학적 성질
Colorless or yellowish transparent liquid용도
1,1,3,3-Tetramethyldisiloxane is used as a monomer in the production of silicone polymers or silicone resins. It is used as a precursor to prepare other organosilicon compounds. It is also utilized in non-aqueous polymer preparation as well as a laboratory reagent.Purification Methods
1,Possible impurity is 1,1,5,5-tetramethyl-3-trimethylsiloxytrisiloxane b 154-155o/733mm. Fractionate it, collect fractions boiling below 80o and re-fractionate it. Its purity can be analysed by alkaline hydrolysis and measuring the volume of H2 liberated followed by gravimetric estimation of silica in the hydrolysate. It is unchanged when stored in glass containers in the absence of moisture for 2-3 weeks. Small amounts of H2 are liberated on long storage. Care should be taken when opening a container due to pressure developed. [Speier et al.
