Problems solved by technology

At present, my country has a large demand for acetic acid. There are many ways to produce acetic acid in industry, but they generally have the following disadvantages: one must be carried out under heating and pressure conditions, which consumes a lot of energy and costs high; the other is that the raw materials are mostly gas, causing the product to be difficult to collect; the third is that there are more impurities in the product

Abstract

The invention relates to the method and apparatus for preparing acetic acid through electrolysis, wherein the apparatus comprises a container, a power source, a graphite layer, a graphite rod and an asbestos diaphragm. The preparing process comprises using silver ammonia solution and acetaldehyde as raw material, producing acetic acid through electrolysis method. The advantages of the invention include simple process for production and lowered production cost.

Description

technical field [0001] The invention relates to a method and equipment for producing acetic acid, in particular to a method for producing acetic acid by electrolysis and a device thereof. Background technique [0002] Acetic acid (acetic acid) is an important organic chemical raw material with a wide range of uses. At present, my country has a large demand for acetic acid. There are many ways to produce acetic acid in industry, but they generally have the following disadvantages: one must be carried out under heating and pressure conditions, which consumes a lot of energy and costs high; the other is that the raw materials are mostly gas, causing the product to be difficult to collect; the third is that there are many impurities in the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an acetic acid electrolysis production method and its device with low production cost and energy saving. [0004] The tech...
