The synthetic alkali of the intermediate is carbonate or the hydroxide of an alkali metal; the reaction temperature is 20-80 DEG C, and the reaction solvent is haloalkane; and in the oxidation reaction, the reaction temperature is 20-100 DEG C, and the reaction time is 1-6 hours. The ...
iboga roots, it is necessary to employ certain substances, such as haloalkanes, alcohols, vinegar, and ammonia (Goldblatt et al., 1970). Laboratory extraction takes place through the use of a Soxhlet apparatus. From 90 kg of T. iboga root, approximately 500 g of pure ibogaine can be ...
2.7.4.7.1 From 1,1,1-trihaloalkanes, amide halides and related compounds The reaction of chloroform with imidazoles,983,984 benzimidazoles985 and secondary amines (especially alicyclic amines) in the presence of alkoxides or hydroxides, as well as the reaction of chlorodifluoromethane with sodiu...
aminobenzine,aniline,aniline oil,phenylamine- oily poisonous liquid amine obtained from nitrobenzene and used to make dyes and plastics and medicines enamine- an amine containing the double bond linkage -C=C-N- alkane,alkane series,methane series,paraffin series,paraffin- a series of non-aromatic ...
Therefore, current methods of synthesizing poly(vinylamine) require either a rigorous purification of the poly(N-vinylformamide), or an extremely long reaction time and a relatively high reaction temperature to ensure that all the residual poly(N-vinylformamide) monomer is consumed during the ...
The yield of nitroalkane is also increased if the reaction is carried out at elevated temperature, since this favors the monomeric rather than the dimeric form of the intermediate nitrosoalkane and allows it to be oxidized further.7 For example, cyclohexylamine gave the dimer of nitrosocyclohexane...
V. Alkylammonium Thiolate and Peroxide Salts; Possible Intermediates in Amine-Catalyzed Oxidation of Mercaptans by Hydroperoxides Aliphatic amines catalyze the reaction of mercaptans and hydroperoxides to yield the corresponding disulfides, alcohols and water. The formation of alkylammonium salts of ...
The reaction can be conducted at a temperature of 80° C. to 110° C., preferably at 90° C. to 100° C. The benzaldehyde that is generated can be removed, for example, by steam distillation and the resulting N-methyl-N-pentylamine can be isolated from the aqueous phase by any ...
Reaction products of amines and polymers containing saturated heterocyclic moieties may be used as levelers in metal electroplating baths. The reaction products may plate metal with
residue of a multifunctional crosslinking agent selected from the group consisting of a dihaloalkane, haloalkyloxirane, alkyloxirane sulfonate, di(haloalkyl)amine, tri(haloalkyl)amine, diepoxide, triepoxide, tetraepoxide, bis(halomethyl)benzene, tri(halomethyl)benzene, and tetra(halomethyl)benzene....
