C7H18O3Si

C7H18O3Si is the chemical formula for several organosilicon compounds. One common interpretation of this formula corresponds to a siloxane derivative, specifically trimethylsilanol, which has the structure (CH3)3SiOH. In this molecule, a silicon atom is bonded to three methyl groups and one hydroxyl group. This compound is a simple silanol, characterized by the Si-OH functional group. Trimethylsilanol can be formed by the hydrolysis of trimethylsilyl chloride or other trimethylsilyl halides. It is a colorless liquid and is soluble in many organic solvents. Its reactivity is typical of silanols, undergoing condensation reactions to form siloxane linkages. It can also react with various reagents to form derivatives.

Another possible isomer for C7H18O3Si could be a silyl ether, such as dimethylethoxysilane, with the structure (CH3)2Si(OC2H5)H. This compound features a silicon atom bonded to two methyl groups, one ethoxy group, and one hydrogen atom. It is a colorless liquid and is flammable. Dimethylethoxysilane can be synthesized through various methods, including the reaction of dimethyldichlorosilane with ethanol followed by reduction. Compounds with the Si-H bond are known for their reducing properties and their ability to participate in hydrosilylation reactions. The specific properties and applications of C7H18O3Si depend heavily on its exact isomeric structure.
