methylamine造句
1 AIM To study whether chronic administration of methylamine may induce elevation of semicarbazide-sensitive amine oxidase (SSAO) activity and initiate the injury of cardiovascular endothelium.
2 Methylamine is the simplest amine, so the study of its energy levels is very important to reveal amines properties.
3 N-Methyl-2-(4-phenoxyphenoxy) acetamide was synthesized from 4-phenoxyphenol and 2-chloroacetyl methylamine with DMF as solvent and potassium carbonate as catalyst.
4 METHODS Plasma SSAO activity, methylamine hydrochloride(MA) and its metabolite formaldehyde(FA) concentrations were determined by HPLC after iv MA to mice, rats and rabbits.
5 Zeolite B-CF-2 was synthesized using granules of boron-containing silicate porous glass in the mixture vapor of methylamine and water at 473 K.
6 Methyl morpholine is synthesized starting from dichloroethyl ether and methylamine and sodium hydroxide.
7 L-RP mainly consists of sulfonated asphalt and inert particles, which has good compatibility with formation characteristics and methylamine system.
8 A review was given on present situation of technology for methylamine synthesis and N, N- dimethylfornanide synthesis. Its development suggestions in China were also summarized.
9 Studies of the Stardust samples by scientists at several NASA centers lend support to this hypothesis, by detecting the presence of two nitrogen-rich organic molecules – methylamine and ethylamine.
10 A further PCA analysis shows that the Smell-seeing sensitive array can discriminate even the class differences among methylamine, ethylamine and isopropylamine .
11 Influences of feedstock ingredients and ratio, water content on methylamine production were analyzed.
12 The ab initio calculations have been performed on the reaction paths of 1, 1- and 1, 2-dehydrogenation of methylamine by the Intrinsic Reaction Coordinate (IRC) method.
13 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.
14 By laser cladding,[www.] the sealing face of the in outlet valve parts in methylamine pump in urea production line has been strengthened.
15 An acid-basic bifunctional amine-hybrid H-Y zeolite has been hydrothermally prepared at 416 K with methylamine solution as a modifier.
16 By adopting FORTRAN language to simulate and calculate the absorbing tower of methylamine tail gas, the filler height and composition of tail gas can be got.
