The bond length for C=N is 1.279 Å, and for the N-C bond it is 1.458 Å. The ∠ C=N-C is 116.6°. [4] The electric dipole moment is 1.53 Debye. [6] When heated to 535°, N-methylmethanimine decomposes to hydrogen cyanide (HCN) and methane (CH 4). [4] Between 400 and 550°C, the cyclic amine, aziridine decomposes to a mixture of N ...
Methylamine has been produced industrially since the 1920s (originally by Commercial Solvents Corporation for dehairing of animal skins). [4] This was made possible by Kazimierz Smoleński [] and his wife Eugenia who discovered amination of alcohols, including methanol, on alumina or kaolin catalyst after WWI, filed two patent applications in 1919 [5] and published an article in 1921.
Urea, also known as carbamide-containing cream, [clarification needed] is used as a medication and applied to the skin to treat dryness and itching such as may occur in psoriasis, dermatitis, or ichthyosis. [1] [2] [3] It may also be used to soften nails. [3] In adults side effects are generally few. [4] It may occasionally cause skin ...
N,N-Diethylmethylamine (diethylmethylamine, DEMA) is a tertiary amine with the formula C 5 H 13 N. N,N-Diethylmethylamine is a clear, colorless to pale yellow liquid at room temperature, and is used in various industrial and scientific applications including water desalination as well as analytical and organic chemistry.

The molecule consists of a nitrogen atom with two methyl substituents and one hydrogen.Dimethylamine is a weak base and the pKa of the ammonium CH 3-NH + 2-CH 3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79).
Calamine, also known as calamine lotion, is a medication made from powdered calamine mineral that is used to treat mild itchiness. [2] [3] Conditions treated include sunburn, insect bites, poison ivy, poison oak, and other mild skin conditions. [4] [5] It may also help dry out secretions resulting from skin irritation. [1]
A further variant is suitable for continuous production, in which ammonia, methanal and hydrogen cyanide react at pH 6 to form iminodiacetonitrile, which in a strongly acidic medium (pH 1.5) reacts with ethanal to produce trinitrile methylglycinonitrile-N,N-diacetonitrile in a very good yield of 92%. (step 1).
Aqueous Cream BP, also known as sorbolene, is a light, hydrocarbon-based emulsion, which is officially registered in the British Pharmacopoeia and categorised by the British National Formulary as a non-proprietary emollient preparation. [1]
