Brine can be contaminated with silica when the production of chlorine is a byproduct of a metal refining process from metal chloride ore. 1, Ohio State Univ., 1955. Then London forces are supposed to be greater in $\ce{SiCl4}$ due to its larger size and its boiling point should be higher than comparatively smaller $\ce{CCl4},$ but $\ce{CCl4}$ has higher boiling point.. After forming bond with four chlorine atoms, silicon gains four more electrons in its valance shell. Thus, the dipole moment of each of the four Si-Cl bond is getting cancelled by the other and the resultant dipole moment will be showing zero. Chlorosilanes, such as SILICON TETRACHLORIDE, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. having technical skill for evaluation under their specific end-use With alcohols and ethanol it reacts to give tetramethyl orthosilicate and tetraethyl orthosilicate: At higher temperatures homologues of silicon tetrachloride can be prepared by the reaction: In fact, the chlorination of silicon is accompanied by the formation of hexachlorodisilane Si2Cl6.
