Silicon tetrachloride reaction with, alcohols

TIN TETRACHLORIDE (7646-78-8) Reacts with moisture in air, forming hydrogen chloride fumes. Reacts with water, producing much heat, hydrochloric acid, tin oxide. Violent reaction with bases, oxidizers, organic materials, phenyl azide, silicon tetrahydride. Contact with alcohols, alkyl nitrates, amines, ethylene oxide, potassium, sodium, turpentine may cause fire and explosions. Contact with ethylene oxide may cause violent polymerization. Incompatible with glycidol. Attacks some plastics, rubber, and coatings. Corrosive to metals, especially in the presence of moisture. 

Of the chemical methods to separate the azeotropic mixture of silicon tetrachloride and trimethylchlorosilane, etherification is the most convenient one. This method is based on the different activity of components in the reactions of partial etherification by alcohols or phenols. Silicon tetrachloride is the first to interact with alcohols or phenols, eventually forming tetraloxy- or tetraaroxysilanes ... 

The reaction of silicon tetrachloride with polyliydric alcohols produces a condensation polymer which may be called a silicon polyester. Some interesting condensation polymers related to these are produced by the reaction of ethyl silicate with glycols and phenols.40... 

Unlike uranium pentachloride, which is thermally unstable, protactinium pentachloride sublimes unchanged above 180°C in vacuo. It is a yellow, moisture-sensitive solid which is slightly soluble in benzene, tetrahydrofuran, and carbon tetrachloride. Visible absorption spectra have been recorded for solutions in the last two solvents and in alcohol (110). Reactions with hydrogen, aluminum, oxygen, and silicon tetra-iodide are discussed below. It is unaffected by carbon monoxide at 350°C in a sealed tube. 

The reactions indicated above occur with primary and secondary alcohols only, and have been studied mainly with ethyl and isopropyl alcohols. With a tertiary alcohol (Bu OH), silicon tetrachloride yields almost quantitatively Si(OH)4 and Bu Cl. This...
