Abstract
The invention relates to a preparation device and method for isooctyl thioglycolate, and particularly to the technical field of chemical intermediate preparation. A synthesis tank and a stirring mechanism are provided, the stirring mechanism is placed in a synthesis space of the synthesis tank, raw materials for isooctyl thioglycolate to be synthesized are placed into the synthesis space of the synthesis tank according to a set molar ratio, a first driving member arranged outside the synthesis tank is connected to a portion of a first stirring member extending out of the synthesis space, and a free end of the first stirring member is connected to a second stirring member via a cross universal joint, a sliding member is slidably sleeved on the outer periphery of the first stirring member, and the sliding member is slidable along the first stirring member until it engages with the cross universal joint. The first driving member drives the first stirring member to rotate, thereby stirring different areas in the synthesis space and uniformly dispersing thioglycolic acid and isooctyl alcohol, thereby improving the manufacturing efficiency of isooctyl thioglycolate.
