ABSTRACT:
A process for the preparation of organic acid halide such as acetyl chloride by reacting an organic acid anhydride with a silicon halide, such as silicon tetrachloride, under conditions such that such the organic acid halide is produced along with silica which is easily separated and disposed of. Preferred conditions include use of a solvent, use of a catalyst and additional process reaction steps whereby by-products are converted to additional organic acid halide and easily disposable waste products.
