(Meth)acrylates of polyhydric alcohols are prepared by reacting (meth)acrylic acid and the corresponding polyhydric alcohol in the presence of at least one acidic catalyst and, if required, at least one polymerization inhibitor and in the presence or absence of a solvent, by a process in which the polyhydric alcohol used contains less than 500 ppm of bound formaldehyde.
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.
