Abstract

This invention concerns a method of charging dry terephthalic acid into a reactor which may contain glycol and be under elevated pressure and elevated temperature. According to the invention a suspension of terephthalic acid in a gas such as nitrogen is formed and this suspension is charged into the reactor.
