Abstract

The invention discloses a centrifugal inner swirl type multiphase jetting reactor and a method for preparing tert-carbonic acid with the multiphase jetting reactor. A cylinder is arranged at the upper end of the reactor, a conical reactor body which is connected with the cylinder and shrinks gradually is arranged at the lower end of the reactor, and the bottom of the conical reactor body is connected with a liquid receiving tank of the cylinder. The method comprises the steps that superfine cuprous oxide powder is added into the reactor in the form of CO gas suspending sol, under the action of liquid strong acid, cuprous oxide suspending particles are mixed in the form of thin film jet flow, subjected to a reaction and converted into a multicarbonyl copper compound, and the multicarbonyl copper compound further reacts with olefin, so that the tert-carbonic acid is prepared. By means of the centrifugal inner swirl type multiphase jetting reactor and the method for preparing tert-carbonic acid with the centrifugal inner swirl type multiphase jetting reactor, preparation of tert-carbonic acid and recycling of unreacted CO are achieved, the problem that in traditional kettle type processes, when cuprous oxide powder and liquid acid are mixed, caking is caused easily is solved, interphase mass transfer efficiency is remarkably improved, production efficiency is greatly improved, olefin polymerization is effectively inhibited, and the reaction yield is raised.

Description

technical field [0001] The invention relates to a centrifugal internal swirling multi-phase jet reactor and a method for preparing tertiary carbonic acid by using the reactor, in particular to a method and a reaction device for preparing copper carbonyl and tertiary carbonic acid by means of enhanced mass transfer by jetting. Background technique [0002] Tertiary carbonic acid, also known as new acid or trialkylacetic acid, is a kind of multi-branched monobasic saturated carboxylic acid, and is an important branch of industrial fatty acids. In the structure of tertiary carbonic acid, due to the steric hindrance caused by the highly branched chain of the tertiary carbon structure, the reaction on the carboxyl group is much more difficult than that of primary carbonic acid and secondary carbonic acid. Therefore, the chemical properties of its ester derivatives are relatively stable. Esters have excellent hydrolysis resistance, heat resistance, weather resistance, discoloratio...
