应用 Poly(methylhydrosiloxane) is used in the reduction of esters to alcohols, catalyzed by a combination of titanocene dichloride and either n-BuLi or EtMgBr. It is a safer alternative to triethoxysilane, B22063, for reduction of phosphine oxides to phosphines, catalyzed by Ti(O-i-Pr)4. It is also used in greener amine synthesis by reductive amination as an alternative to borohydrides. 备注 Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Incompatible with strong oxidizing agents, amines and bases. 基本信息 MDL MFCD00084478 分子式 (CH3)3SiO[(CH3)HSiO]nSi(CH3) 分子量 ca 1900 闪点 204°(399°F) 密度 1.006 折射率 1.3980 灵敏度 Ambient temperatures. 形态 Liquid 溶解性 Not miscible or difficult to mix in water. 安全信息 TSCA 是 |
