甲胺

Methanimidamide monoacetate was synthesized by hydrogenation of cyanamide over Pd-In/C catalyst in the presence of acetate acid.

采用以活性炭为载体负载Pd、In制备的催化剂，在醋酸存在条件下，将氰胺加氢合成醋酸甲脒。

A new synthesis process for chloroform and dimethylformamide by the reaction of alkalizing and deacidifying chlorine oil and dimethylamine was studied.

研究了氯油加碱除酸后和二甲胺水溶液反应制备氯仿和N，N-二甲基甲酰胺的新工艺路线，通过正交实验对工艺条件进行优化，得到的优化合成工艺条件为：反应温度为50℃，保温反应时间为60min，n∶n=1∶1.10。

The main photoproducts in dioxane and hexane are 2-chloro benzamide and 4-chlorophenyl isocyanate.

在二氧六环及正己烷中的主要光解产物为邻氯苯甲酰胺和对氯苯基异氰酸酯。

Tests with diphenylamine,formaldehyde,and staining with acridine orange as well as the curves of thermal denaturation showed that this strain of virus had a single-stranded DNA.

电镜下经甲酰胺法展层的病毒核酸呈单链线状，分子量平均为2.1×106道尔顿。53s中空的圆形子粒，有很强的血凝性，而对照组铁蛋白和同一条件下所制备正常兔肝成份无凝血特性，说明53s的9nm粒子应为病毒外壳蛋白子粒。

MARKET FORECAST: N, N-dimethylformamide is a basic chemical material and an excellent organic dissolvent.

市场分析：N，N-二甲基甲酰胺是一种基本有机化工原料和优良的有机非质子极性溶剂。

The resultshows that it is possible to obtain the natural abundance 15N NMRspectra of solids under the DNP enhancement.

对掺杂了稳定自由基的15N富集苯甲酰胺样品进行了DNP增强实验，15N的DNP增强至少为1000倍，这说明在DNP增强下，获得天然丰度样品的15N NMR谱是可能的。

Methods 44 patients with septic shock were divided into two groups of Dopa group and NE group randomly.

选择ICU早期感染性休克患者44例为研究对象，随机分成多巴胺组和去甲肾上腺素组。

The trial included 1679 patients, of whom 858 were assigned to dopamine and 821 to norepinephrine.

这个试验总共纳入1679例病人，其中858人归属于多巴胺组，821人归属于去甲肾上腺素组。

For this reason, the best entrainer would be N,N-dimethylformamide.

由于这个原因，最好的共溶剂应是N，N-二甲基甲酰胺。

Based on the results presented in this paper, it can be concluded that N,N-dimethylformamide is the most promising entrainer.

根据本文的结果可以得出结论，N，N－二甲基甲酰胺是最有希望的共溶剂。
