1, The select(?)ve synthesis of dimethylamine from ammonia and methylalcohol using the cation modified mordenite as catalysts on atmospheric pressure fixed bed have been studied.

2, Alkyl dimethylamine is made from fatly alcohol and dimethyla - mine by one stage catalysis.

3, Alkyl dimethylamine is made from fatty alcohol and dimethylamine by one stage catalysis.

4, Elementary reaction pathways of the reductants such as dimethylamine borane, hypophosphite ion, formaldehyde, and titanium trichloride were quantitatively examined in terms of the heat of reaction.

5, Amphoteric monomer is prepared with acrylic acid , dimethylamine and chloroethanol by Mannich reaction.

6, A new technology for preparation of Ethoprophos Diethyl Dithiophosphoric acid ,[http://sentencedict.com/dimethylamine.html] Propance Bromide and Dimethylamine was introduced.

7, Linen was chemically modified by the synthetic product of polyepichlorohydrin and dimethylamine, so as to improve its dye uptake and dyeing behaviour.

8, The second is the preparation of sodium N, N-dimethyldithiocarbamate (SDDC) by the reaction of dimethylamine and carbon disulfide.

9, Ziram was synthesized in an one-step with aqueous solution of dimethylamine carbon disulfide and zinc oxide, in yield 97%. waste water is reused.

10, Influences of feedstock ingredients and ratio, water content on methylamine production were analyzed. The yield of dimethylamine can be moderately increased by adjusting the ratio of feedstock.

11, The silicone quaternary was synthesized reaction of - H silicone, unsaturated - ether, chloroacetic acid, dimethylamine.

12, High boiling solvent (HBS) lignin amine was prepared by Mannich reaction with dimethylamine. The adsorption of HBS lignin amine and bromelain was investigated.
