Chain Decomposition of Aqueous Trietanolamine

Schwarz, Harold A.

, p. 3431 - 3435 (1982)

A radiation-induced chain decomposition of aqueous triethanolamine into acetaldehyde and diethanolamine is reported.Chain length over 1000 have been observed, depending on pH, concentration, and radiation intensity.The chain propagation steps include OH group migration in the 2-hydroxy-1-(diethanolamino)ethyl radical and NR2 migration in 1-hydroxy-2-(diethanolamine)ethyl radical, each producing a 2-hydroxy-2-(diethanolamine)ethyl radical.Free-radical spectra and rate constants are given.Studies of diethanolamine and diethylethanolamine solutions gave similar free-radical spectra but much shorter chains.

Lipase-catalyzed synthesis of fatty acid diethanolamides.

Liu,Nag,Shaw

, p. 5761 - 5764 (2001)

Diethanolamides are nonionic emulsifiers widely used in industries such as cosmetics and as corrosion inhibitors. Candida antarctica lipase (Novozym 435) was used to catalyze the amidation of various fatty acids with diethanolamine. Contents of fatty acid

Temperature dependency of the equilibrium constant for the formation of carbamate from diethanolamine

Aroua,Amor,Haji-Sulaiman

, p. 692 - 696 (1997)

The equilibrium constant for the formation of diethanolamine carbamate was determined experimentally at (303, 313, 323, and 331) K for ionic strengths up to 1.8 mol dm-3, the inert electrolyte being NaClO4. A linear relationship was found to hold between log K and I0.5. The thermodynamical constant has been determined and expressed by the equation log K1 = -5.12 + 1.781 × 103 K/T.

A Modified Method for the Determination of N-Nitrosodiethanolamine in Coconut Diethanolamide Using HPLC with Dual-Wavelength UV-Vis Detector

Mostafalu, Ramin,Banaei, Abbas,Riazi, Mohammad Hadi,Ghorbani, Fatemeh

, p. 431 - 435 (2016)

A simple and novel method based on high-performance liquid chromatography with dual-wavelength ultraviolet detection at 234 and 254 nm has been developed for the determination of underivatized N-nitrosodiethanolamine in coconut diethanolamide. The correlation coefficient obtained shows that the method is correct.

Boronic Ester Based Vitrimers with Enhanced Stability via Internal Boron-Nitrogen Coordination

Zhang, Xiaoting,Wang, Shujuan,Jiang, Zikang,Li, Yu,Jing, Xinli

supporting information, p. 21852 - 21860 (2021/01/11)

Boron-containing polymers have many applications resulting from their prominent properties. Organoboron species with reversible B-O bonds have been successfully employed for the fabrication of various self-healing/healable and reprocessable polymers. However, the application of the polymers containing boronic ester or boroxine linkages is limited because of their instability to water. Herein, we report the hydrolytic stability and dynamic covalent chemistry of the nitrogen-coordinating cyclic boronic diester (NCB) linkages, and a new class of vitrimers based on NCB linkages is developed through the chemical reactions of reactive hydrogen with isocyanate. Thermodynamic and kinetic studies demonstrated that NCB linkages exhibit enhanced water and heat resistance, whereas the exchange reactions between NCB linkages can take place upon heating without any catalyst. The model compounds of NCBC-X1 and NCBC-X2 containing a urethane group and urea group, respectively, also showed higher hydrolytic stability compared to that of conventional boronic esters. Polyurethane vitrimers and poly(urea-urethane) vitrimers based on NCB linkages exhibited excellent solvent resistance and mechanical properties like general thermosets, which can be repaired, reprocessed, and recycled via the transesterification of NCB linkages upon heating. Especially, vitrimers based on NCB linkages presented improved stability to water and heat compared to those through conventional boronic esters because of the existence of N → B internal coordination. We anticipate that this work will provide a new strategy for designing the next generation of sustainable materials.

PROCESS FOR PRODUCING ALKANOLAMINE

-

Paragraph 0046-0053, (2019/02/19)

The present invention provides a method of producing an ethanolamine, with a low production ratio of a dialkanolamine (for example, less than 30% by weight). A process for producing an alkanolamine of the present invention includes reacting an alkylene oxide with ammonia to obtain a reaction product containing a monoalkanolamine, a dialkanolamine, and a trialkanolamine; separating the dialkanolamine from the reaction product; and recycling at least a portion of the dialkanolamine for the reaction of an alkylene oxide with ammonia, wherein in the recycling step, the dialkanolamine is supplied in a molar ratio of the alkylene oxide (moles) to a total amount (moles) of ammonia and the dialkanolamine of 0.08 or more and less than 0.26.

METHOD FOR PRODUCING CIS- AND TRANS-ENRICHED MDACH

-

, (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.

AgI/TMG-Promoted Cascade Reaction of Propargyl Alcohols, Carbon Dioxide, and 2-Aminoethanols to 2-Oxazolidinones

Li, Xue-Dong,Song, Qing-Wen,Lang, Xian-Dong,Chang, Yao,He, Liang-Nian

, p. 3182 - 3188 (2017/10/03)

Chemical valorization of CO2 to access various value-added compounds has been a long-term and challenging objective from the viewpoint of sustainable chemistry. Herein, a one-pot three-component reaction of terminal propargyl alcohols, CO2, and 2-aminoethanols was developed for the synthesis of 2-oxazolidinones and an equal amount of α-hydroxyl ketones promoted by Ag2O/TMG (1,1,3,3-tetramethylguanidine) with a TON (turnover number) of up to 1260. By addition of terminal propargyl alcohol, the thermodynamic disadvantage of the conventional 2-aminoethanol/CO2 coupling was ameliorated. Mechanistic investigations including control experiments, DFT calculation, kinetic and NMR studies suggest that the reaction proceeds through a cascade pathway and TMG could activate propargyl alcohol and 2-aminoethanol through the formation of hydrogen bonds and also activate CO2.
