Abstract

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.

Description

technical field [0001] The invention relates to the technical field of rectification towers, in particular to a special rectification tower for the purification and preparation of pivaloyl chloride. Background technique [0002] There are many rectification tower devices on the market today, but the rectification towers on the market have become a troublesome problem for the majority of users due to their incomplete technical production. On the one hand, the rectification towers on the market cannot be used to extract solutions To high-precision purification, on the other hand, the rectification towers on the market do not have a set of reasonable and simple materials for purifying gaseous solutions. This set of special distillation tower for the pure preparation of pivaloyl chloride can extract high-precision pivaloyl chloride and other solutions, which is convenient for chemical users to use. Contents of the invention [0003] The purpose of the invention is in order to...
