A method for preparing alkyl amine
-
Paragraph 0066-0069, (2017/07/12)
The invention discloses a preparation method for alkyl alcohol amine. The preparation method comprises the following steps: (1) feeding alkyl amine and a reaction promoter alkanolamine into a reaction kettle for stirring and mixing; (2) adding epoxy alkane for synthesis, wherein the feeding molar ratio of epoxy alkane for synthesis to alkyl amine is higher than the theoretical reaction molar ratio; (3) after the feeding is finished, carrying out heating and pressurization; (4) carrying out heat preservation conversion rate to obtain a crude product; (5) conducting continuous distillation on the crude product to separate out alkyl alcohol amine. During the preparation, alkanolamine is primary alkanolamine or secondary alkanolamine. Compared with the prior art, the preparation method provided by the invention adopts the technical scheme that alkanolamine is taken as the reaction promoter instead of water as a catalyst, so that the conversion rate of alkyl amine can reach 99.0% in general, the highest conversion rate can reach 99.9%, and the highest recovery rate of alkyl alcohol amine can reach 99.8%. Therefore, the preparation method provided by the invention has the advantages of being high in raw material conversion rate and recovery rate.
Aminimide derived from benzoylformic acid ester as photolatent base/radical initiator
Kirino, Manabu,Tomita, Ikuyoshi
experimental part, p. 1556 - 1563 (2012/06/04)
An aminimide possessing a benzoyl substituent, 1,1-dimethyl-1-(2- hydroxypropyl)amine benzoylformimide (BFI), proved to serve as an excellent photobase catalyst. BFI decomposes smoothly by the UV irradiation to give products containing tertiary amines. The effective nature of BFI as a photo/thermal dual-base catalyst was convinced by the thermal and photoinduced polymerization of epoxide/thiol system. Based on the facts that the mixture of BFI and epoxide/thiol exhibit a long pot life in dark and that it undergoes smooth polymerization by UV irradiation and heating, it was supported that BFI serves as an efficient photo/thermal latent dual-base catalysts. It was also found that BFI initiates the free radical polymerization of vinyl monomers such as 2-hydroxylethyl methacrylate (HEMA) under the UV irradiation while the mixture of BFI and HEMA also exhibit a long pot life in dark, indicating the excellent ability of BFI as a photoradical initiator.
Processes for the preparation of aminoethers
-
, (2008/06/13)
A process for preparing aminoethers, particularly bis[2-(N,N-dialkylamino)alkyl]ethers, which comprises contacting a carboxylated aminoether with a metal oxide catalyst under conditions effective to produce the aminoether. Many of these aminoethers are useful as catalysts in the production of polyurethanes, especially cellular polyurethanes.
