Abstract

The invention provides a novel batching kettle for preparing a urea-fatty alcohol mixed solution and a use method thereof, and relates to the field of batching kettles. The novel batching kettle for preparing the urea-fatty alcohol mixed solution comprises a mixing tank, a mixing stirrer, a condenser, a shearing cylinder and a shearing stirrer, wherein the mixing tank consists of a mixing tank upper sealing head, a mixing tank cylinder and a mixing tank lower sealing head; and the mixing tank upper sealing head is provided with a shearing cylinder insertion port, a pressure gauge interface, a fatty alcohol inlet, a gas phase channel and a catalyst adding port. According to the invention, the condenser is arranged on a gas channel of the mixing tank, so fatty alcohol vaporized by providing of partial pressure can be condensed into liquid which directly flows back into the mixing tank, waste of the fatty alcohol is effectively reduced, environmental pollution is avoided, and the purposes of saving energy and protecting environmental are achieved; and a mixed material of the fatty alcohol, the urea and a catalyst is prepared under the condition of 25-60 DEG C, so the reaction of the fatty alcohol and the urea in a batching process can be effectively reduced, and the purpose of environmental protection is achieved.

Description

technical field [0001] The invention relates to the technical field of batching kettles, in particular to a novel batching kettle for preparing urea-fatty-alcohol mixed liquid and a method for using the same. Background technique [0002] The technology of preparing organic carbonates such as dimethyl carbonate, diethyl carbonate, ethylene carbonate and glycerol carbonate from urea and fatty alcohols such as methanol, ethanol, ethylene glycol and glycerol is easy to obtain raw materials, low cost and easy to process. The characteristics of safety and environmental protection have been paid more and more attention by the industry, and some industrial application demonstrations have been realized. At present, the industrial preparation of organic carbonate from urea and fatty alcohol basically consists of ingredients, reaction, ammonia recovery, and organic carbonate refining. consists of four processes. [0003] The so-called batching refers to putting urea, fatty alcohol an...
