Molar volume (m3/mol): 156.0 3、 Isotropic specific volume (90.2K): 378.7 4、 Surface tension (dyne/cm): 34.6 5、 Dielectric constant (F/m): not available 6、 Dipole distance (D): not available 7、 Polarization rate (10 -24cm 3): 17.22 Oil-water partition coefficient / LogP. LogP value refers to the logarithmic value of the partition coefficient of a substance in the n-octanol/water two-phase system, reflecting the partition of the substance in the oil-water two-phase. The larger the LogP value, the more lipophilic the substance is; conversely, the smaller the LogP value, the more hydrophilic the substance is. Product use. Trimethylhydroxyethyl ethylenediamine is a low odor reactive foaming catalyst. Trimethylhydroxyethyl ethylene diamine is mainly used as a catalyst for polyether-based polyurethane flexible foam, molded foam, semi-rigid foam and rigid foam, and is especially recommended for automotive foam.

DMAEE CAS:1704-62-7 Usage and Manufacturing Method Brief introduction. Dimethyldiethanolamine is a chemical substance. Alias: Dimethylaminoethoxyethanol Abbreviation: DMAEE English name: dimethyaminoethoxyethanol, dimethyl2-(2-aminoethoxy)ethanol Molecular formula: C6H15NO2 Relative molecular weight:133.2 CAS No.:1704-62-7 Formulation. Recipe weight:133.19 Purity percentage: ≥98.0% (GC) Physical form: Liquid Experimental operation. [ 50-00-0 ] + [ 929-06-6 ] = [ 1704-62-7 ] Phase I: 0.5 hr. Phase II: 100 - 110 °C; 2 h. Phase III: 120 °C; 4 h. Synthesis To a 250 ml three-necked flask was added 63.1 g of diethyleneglycolamine (0.6 mol), 34.5 g of paraformaldehyde (1.2 mol), stirred for 30 min and 63 g of formic acid (1.2 mol, 88%) was added dropwise at a temperature of 100 to 110 °C and reacted at about 100 °C for 1 h. Distill out 30 g under reduced pressure (vacuum - 0.094 MPa, kettle temperature 80°C). The distillation ended with 90.0% product and 9.8% impurity (S-2) content. _: The liquid from step 2) was transferred to a 500 ml distillation flask and distilled under reduced pressure at a vacuum of -0.094 mpa. 62°C component was n-butanol ester exchanged down to formic acid as butanol, 121° C DMAEE component that is the product. Collected 121 ° C component 128.3g, yield 96.5%, the Uses. DMAEE is a low odor reactive foaming catalyst, mainly used in rigid packaging foam, also used in molded flexible foam and polyether urethane flexible foam.DMAEE is also an important intermediate, used in polyurethane coatings, surfactants, mine reinforcement and many other fields. Zhongke's organic amine catalyst and curing agent series products will be put into production one after another, and the core catalyst and curing agent products will be used as the basis for the subsequent development of new materials for high value-added polyurethane and epoxy resin by precisely matching the market changes. Integrated manufacturing method of dmae and dmaee in microtubular reactor. A method of integrated preparation of DMAE and DMAEE in microtube reactor is disclosed, which includes the following steps in turn: pumping ethylene oxide and aqueous dimethylamine solution formed by mixing dimethylamine with water as catalyst as materials into the microtube reactor respectively, controlling the molar ratio of ethylene oxide to dimethylamine as 1~2:1; setting the reaction temperature in the microtube reactor as 60~90°C and pressure as 1.3 ±0.2 Pa, and the residence time of the material in the microtubular reactor is controlled to be 15～90s; the effluent from the microtubular reactor is an aqueous solution of DMAE and DMAEE. The method of the present invention has the advantages of high atomic economy, good reaction selectivity, mild reaction conditions, short reaction time, simple catalyst, and simple product separation.
