Abstract
This invention provides a process which comprises mixing at least one phenol with a 1-bromopropane product mixture to form a phenol-containing 1-bromopropane product mixture, and recovering a purified 1-bromopropane product from the phenol-containing 1-bromopropane product mixture. This invention also provides a process for preparing a 1-bromopropane product mixture from 1-propanol and hydrogen bromide, characterized by mixing at least one phenol with the 1-bromopropane product mixture to form a phenol-containing 1-bromopropane product mixture, and recovering a purified 1-bromopropane product from the phenol-containing 1-bromopropane product mixture.

A process which comprises mixing at least one phenol with a 1-bromopropane product mixture to form a phenol-containing 1-bromopropane product mixture, and recovering a purified 1-bromopropane product from said phenol-containing 1-bromopropane product mixture, wherein (I) said phenol is mixed with said 1-bromopropane product mixture in proportions of at least about 0.5 part by weight phenol per 1000 parts by weight 1-bromopropane product mixture, and (ii) said phenol is at least one mononuclear phenol having one or two hydroxyl groups directly bonded to the benzene ring and a total of 6 to 16 carbon atoms in the molecule, said at least one phenol being free of unsaturation other than the aromatic unsaturation of the benzene ring.
A process for preparing a 1-bromopropane product mixture from 1-propanol and hydrogen bromide, characterized by mixing at least one phenol with said 1-bromopropane product mixture to form a phenol-containing 1-bromopropane product mixture, and recovering a purified 1-bromopropane product from said phenol-containing 1-bromopropane product mixture, wherein (I) said phenol is mixed with said 1-bromopropane product mixture in proportions of at least about 0.5 part by weight phenol per 1000 parts by weight 1-bromopropane product mixture, and (ii) said phenol is at least one mononuclear phenol having one or two hydroxyl groups directly bonded to the benzene ring and a total of 6 to 16 carbon atoms in the molecule, said at least one phenol being free of unsaturation other than the aromatic unsaturation of the benzene ring.
