performing a reaction of vanillin and ammonium formate to obtain vanillic amine, acidifying the vanillic amine, neutralizing the vanillic amine by using alkali liquid, and performing a reaction of the treated vanillic amine and the para-8-methyl-5-nonene acyl chloride to obtain the finished product...
The organic amine may also be chosen from organic amines of heterocyclic type. Besides histidine that has already been mentioned in the amino acids, mention may in particular be made of pyridine, piperidine, imidazole, triazole, tetrazole and benzimidazole. Preferably, the basifying agent(s) presen...

for example, from neutral, acidic, and cationic nitrobenzene dyes; neutral, acidic, and cationic azo direct dyes; neutral, acidic, and cationic quinone, such as anthraquinone, direct dyes; azine direct dyes; methine, azomethine, triarylmethane, and indoamine direct dyes; and natural direct dyes....
1. Dye composition for dyeing keratin fibres, comprising, in a suitable dyeing medium, at least one cationic tertiary para-phenylenediamine containing a pyrrolidine nucleus i.e. a para-phenylenediamine containing an NHgroup and, in the para position, a disubstituted amine function whose substitutions...
A mechanism involving formation of an S2‐type transition state between the amine nucleophiles and the benzyl bromide and its subsequent decomposition is proposed. Hammett's reaction constant ρ of the reaction decreases with an increase in temperature. Activation parameters were calculated and discussed...
