The invention discloses a special
distillation tower for the pure preparation of
pivaloyl chloride, which comprises a
thermometer, a rectification
tower, a V-shaped connector, a
test tube, a rubber interface and a
titration port. A
distillation head is installed under the
thermometer, and a
distillation head is installed under the distillation head A rectification
tower is installed, a round-bottom
beaker is installed under the rectification tower, and a V-shaped connector is installed on the right side above the round-bottom
beaker, and a condensation
pipe is installed under the right side of the V-shaped connector, and the inside of the condensation
pipe A
test tube is installed on the right side, a water inlet
pipe is installed under the right side of the
test tube, and a rubber interface is installed on the right side of the water inlet pipe, a fixing ring is installed under the right side of the rubber interface, and a
titration port is installed on the right side below the fixing ring, A receiving
bottle is installed under the
titration port, glass beads are installed under the interior of the rectification tower, and a
metal wire is installed under the glass beads. In the present invention, by installing
inert materials inside the rectification tower, the gas solution can be purified to achieve precision purification.
