Methylamine, also known as methanamine, is an organic compound with a formula of CH 3 NH 2. This colorless gas is a derivative of ammonia, but with one hydrogen atom being replaced by a methyl group. It is the simplest primary amine.

2004年9月16日 · Used for making pharmaceuticals, insecticides, paint removers, surfactants, rubber chemicals. Methylamine is the simplest of the methylamines, consisting of ammonia bearing a single methyl substituent. It has a role as a mouse metabolite. It is a primary aliphatic amine, a one- carbon compound and a member of methylamines.

Imines can be hydrolyzed back to the corresponding 1 o amine under acidic conditions. A wide variety of substances with −NH 2 groups can react with aldehydes and ketones by an addition-elimination sequence to yield compounds with a carbon-nitrogen double bond.

2022年7月21日 · The CH 3 NH 2 is organic and comprises a methyl(CH 3) and amino(NH 2) group. Single bonds are formed between the Nitrogen, Carbon, and surrounding Hydrogen atoms. There is also a lone pair attached to the Nitrogen atom. The hybridization of the central Nitrogen and Carbon atoms in Methylamine is sp 3.

2021年9月7日 · 二甲胺是一种有机化合物，分子式 (CH3)2NH。 这种仲胺是一种无色易燃气体，具有氨味和鱼腥味。 最常见的是二甲胺的40%水溶液。 在2005年，大约27万吨二甲胺被生产出来。 二甲胺分子包括一个被两个甲基取代且连有一个氢的氮。 二甲胺是一个碱，其对应的季铵盐CH3-NH2+-CH3的pKa为10.73，超过了甲胺（10.64）和三甲胺（9.79）。 二甲胺可以与酸反应得到盐，比如盐酸二甲胺，一种无味的白色固体，熔点171.5 °C。 二甲胺可通过甲醇和氨在高温和高 …

1998年10月30日 · It is known that for the hydrogen abstraction reaction NH 2 (X ̃ 2 B 1)+CH 4 → NH 3 +CH 3 the forward rate constants were investigated experimentally by different methods 1, 2, 3, 4, i.e. by the laser resonance absorption for detection of NH 2, Demissy and Lesclaux [1] gave the rate constant expression k=5×10 11 exp(−43 kJ mol −1 /RT ...

2021年9月1日 · Congratulations to Olivia Bercher, Shane Plunkett, and Tom Mortimer for their development of a nickel-catalyzed reductive methylation of alkylpyridinium salts (link)! This method enables amino groups to be converted into methyls via pyridinium salt intermediates. This entry was posted in News by mpwatson. Bookmark the permalink.

2023年1月23日 · It is useful to compare the boiling point of methylamine, CH 3 NH 2, with that of ethane, CH 3 CH 3. Both molecules contain the same number of electrons and have, as near as makes no difference, the same shape. However, the boiling point of methylamine is -6.3°C, whereas ethane's boiling point is much lower at -88.6°C.
