Trimethyl acetic acid used as a pesticide, pharmaceuticals, dyes intermediates, also used in high-grade paints, polymerization initiator, photographic materials, spices, oil,

Production methods

1. ISO-butyl alcohol and carboxylic acid in the presence of concentrated sulfuric acid the reaction tert-valeric acid. 2. join the sulfuric acid autoclave, using a replacement kettle for carbon monoxide in the air, and then filled with carbon monoxide up to 5MPa. Metering pump joined isobutene chloroform mixture. About 5MPa, stirred at room temperature for half an hour, after pressure relief materials poured out to ice water, mixing 15min at 5-15. Get chloroform layer with anhydrous sodium sulfate drying, distillation, collecting 65-70 (2.67kPa) fraction, purity of trimethyl acetic acid 97%. Yield of 74%. 3. the tert-butyl alcohol and carboxylic acid (98%) in the presence of concentrated sulfuric acid reaction system.
