Application | used as intermediate of medicine, pesticide and dye used in condensation of glycidyl Ester, medicine, pesticide, dye Intermediates. |
production method | tert-butyl alcohol was added to a mixture of Chloroacetyl Chloride and N,N-dimethylaniline, maintaining the temperature below 30 °c. The reaction mixture was poured into water, washed and dried, and then subjected to fractional distillation under reduced pressure. Fractions of 48-49 ° C. (1.46kPa) were collected to obtain tert-butyl chloroacetate in a yield of 63%. |
