Problems solved by technology

[0003] In the process of the hydrogenation reaction, a hydrogenation reactor is required for processing. The traditional hydrogenation reactor is more traditional in stirring during the reaction, which easily causes the material to not react with hydrogen more quickly and uniformly, which greatly affects the Reduced productivity and quality

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] In the specific implementation process, such as figure 1 As shown, a hydrogenation reaction method for the production of isomerized dodecane is used in conjunction with a high-efficiency hydrogenation reactor, and the method comprises the following steps:

[0034] 1), isobutene trimer (TIB, trimeric isobutene) reacts with hydrogen in an efficient hydrogenation reactor to prepare isododecane;

[0035] 2) The crude isododecane at the outlet of the efficient hydrogenation reactor is dehydrated and dried, then enters the first-level deodorization adsorption tower, and then enters the protection deodorization tower to obtain the finished isododecane;

[0036] Wherein the efficient hydrogenation reactor described in step 1) comprises a mobile platform 1, a support column 2 and a reactor body 3, the middle part of the upper surface of the mobile platfo...

Abstract

The invention provides a hydrogenation reaction method for isododecane production, an efficient hydrogenation reactor is used in cooperation, and the method comprises the following steps: 1) isobutylene tripolymer (TIB, tripolyisobutylene) reacts with hydrogen in the efficient hydrogenation reactor to prepare isododecane; 2) dehydrating and drying the crude isododecane at the outlet of the high-efficiency hydrogenation reactor, feeding the crude isododecane into a primary deodorization adsorption tower, and then feeding the crude isododecane into a protective deodorization tower to prepare a finished product isododecane; wherein the efficient hydrogenation reactor in the step 1) comprises a moving platform, supporting columns and a reactor body, the supporting columns are fixed to the middle of the upper surface of the moving platform at equal intervals, and the reactor body is fixed to the tops of the four supporting columns; by arranging the efficient stirring assembly 8, the efficiency and quality of material mixing and stirring can be greatly improved, compared with a traditional hydrogenation reactor, the production efficiency and quality of isododecane can be effectively improved, and use by people is facilitated.

Description

technical field [0001] The invention relates to the technical field of iso-dodecane production equipment, in particular to a hydrogenation reaction method for iso-dodecane production. Background technique [0002] Isododecane is a highly branched saturated dodecane, which does not have the oily smell of low-carbon alkanes, and has a relatively fast volatilization speed. It can be used as a substitute for volatile silicone oil for The skin feels very refreshing in cosmetics, and can be widely used in various cosmetics, skin care / hair care products, aerosols, etc. Isododecane usually comes from the hydrogenation of isobutylene trimer (TIB). (TIB) is put into the hydrogenation reactor for hydrogenation reaction, so that the crude isomerized dodecane is produced, and then the isomerized dodecane can be obtained through dehydration, drying and deodorization; [0003] In the process of the hydrogenation reaction, a hydrogenation reactor is required for processing. The traditional...
