Some new 2-γ-N-(aminoethyl)aminopropyl-2-methyl-1,3-dioxa-6-aza-2- silacyclooctane and 2-γ-N-(aminoethyl)aminopropyl-2-methyl-6-alkyl(aryl)-1,3-dioxa-6-aza- 2-silacyclooctanes have been synthesized from γ-chloropropyldimethoxymethyl silane by ethylenediamine substitution and diethanolamine or N-alkyl(aryl)diethanolamines substitution. The resulting silocanes have been characterized by elemental analyses, IR, and 1H NMR.

The invention belongs to the field of organic synthesis, in particular relates to a butyl diethanolamine synthetic method, comprises the following steps: (1) diethanolamine with butyraldehyde reaction generates a second ethanol butyl imine; (2) two ethanol-butyl imine reacts with hydrogen to produce butyl diethanolamine. The method of the invention the catalyst that is used for ordinary, cheap and easy to obtain. The hydrogen reduction adopting the common high-pressure autoclave (pressure 10.0 mpa) equipment of the price is cheap, easily purchased. The method of the invention has industrial application value. The products of this invention have high yield, and high purity of the product. Synthesis method of the invention the process is simple, easy separation for products. By a simple fractionation can realize the separation of the product.

, (2017/09/23)
A process for preparing trans-enriched MDACH, including: distilling an MDACH starting mixture in the presence of an auxiliary, which is an organic compound having a molar mass of 62 to 500 g/mol, a boiling point at least 5° C. above the boiling point of cis,cis-2,6-diamino-1-methylcyclohexane, and 2 to 4 functional groups, each of which is independently an alcohol group or a primary, secondary or tertiary amino group. The MDACH starting mixture includes 0 to 100% by weight of 2,4-MDACH and 0 to 100% by weight of 2,6-MDACH, based on the total amount of MDACH present in the MDACH starting mixture. The MDACH starting mixture includes both trans and cis isomers. Trans-enriched MDACH includes 0 to 100% by weight of 2,4-MDACH and 0 to 100% by weight of 2,6-MDACH, where the proportion of trans isomers in the mixture is higher than the proportion of trans isomers in the MDACH starting mixture.
