| titleOfInvention | By the method for the thick cyclic ethers of ethanolamine treatment with by its obtained smart cyclic ethers |
| abstract | The present invention relates to the method for the thick cyclic ethers of a kind of ethanolamine treatment, described thick cyclic ethers comprises 2-20 carbon atom, and the method comprises: 1) in thick cyclic ethers, add thanomin, carries out reflux condensation mode after being heated above the boiling point of thick cyclic ethers; 2) by step 1) mixture that obtains carries out layering; 3) in step 2) add thanomin in lower coarse cyclic ethers after layering, carry out reflux condensation mode after being heated above the boiling point of thick cyclic ethers; With 4) by step 3) mixture that obtains carries out layering, obtains the cyclic ethers after lower floor's process.Technological process of the present invention is not too fierce, easily controls, and yield is improved further.The invention still further relates to the smart cyclic ethers obtained by aforesaid method, the ultraviolet reductibility of this smart cyclic ethers is little, and total yield is high, and without obvious irritating smell. |
