Uses

N-Butyldiethanolamine (H2bdea, N-n-butyldiethanolamine) has been used in the synthesis of the following complexes (Hdnba = 3,5-dinitrobenzoic acid, Hpta = p-toluic acid, H2tpa = terephthalic acid):new mononuclear [Cu(Hbdea)2]·2Hdnba , dinuclear [Cu2(μ-Hbdea)2(N3)2] and [Cu2(μ-Hbdea)2(pta)2]·2H2O1D polymeric [Cu2(μ-Hbdea)2(μ-tpa)]n·2nH2O copper(II) compoundstetranuclear 3d-4f single-molecule magnet (SMM) complexes

General Description

N-Butyldiethanolamine (N-n-butyldiethanolamine) is a tertiary amine. It acts as an N-substituted diethanolamine ligand. It reacts with chromium(II) and lanthanide(III)/rare earth salts (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y) in the presence of coligands to afford three series of isostructural 1:1 3d(Cr(III))/4f(Ln(III)) coordination cluster compounds.

Flammability and Explosibility

Nonflammable

Safety Profile

Mddly toxic via ingestion. A skin and severe eye irritant. Combustible when exposed to heat or flame. To fight fire, use alcohol foam, foam, CO2, dry chemical. Incompatible with oxidizing materials. When heated to decomposition it emits toxic fumes of NOx. See also AMINES.

Synthesis of 2-γ-N-(aminoethyl)aminopropyl-2-methyl-6-alkyl(aryl,H)-1,3-dioxa-6- aza-2-silacyclooctanes

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.

A butyl diethanolamine synthetic method

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.

By a simple fractionation can realize the separation of the product.

METHOD FOR PRODUCING CIS- AND TRANS-ENRICHED MDACH

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.
