Properties and stability
Avoid contact with strong oxidants, strong alkali, and water.
Storage method
Stored in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Keep container tightly sealed. They should be stored separately from oxidants, alkalis, food chemicals, etc., and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
Add tert-butanol to the mixture of chloroacetyl chloride and N,N-dimethylaniline and keep the temperature below 30°C. Pour the reactant into water, wash and dry, and then carry out fractionation under reduced pressure. Collect the 48-49°C (1.46kPa) fraction to obtain tert-butyl chloroacetate with a yield of 63%.
Purpose
Used for the condensation of glycidic acid esters.
