摘要： Process for the continuous production of 3,3'-dichloro-benzidine dihydrochloride from 2-2'-dichloro-hydrazobenzole by treatment with aqueous sulphuric acid by continuously adding to the 2-2'-dichlorohydrazobenzole dissolved in an aromatic solvent which is not miscible with water, at about 20 to 50 °C in the presence of an alkaline metal salt of an alkyl(C8-C23) polyglycol ether sulphate, such a quantity of 50 to 80 % aqueous sulphuric acid that the suspension formed remains transportable and then also continuously diluting the suspension emerging from the reaction region with water and heating it to about 90 to 95 °C until a solution is obtained, separating the aromatic solvent from the hot sulphuric acid aqueous phase, causing the 3-3'-dichloro-benzidine dihydrochloride to precipitate by the addition of hydrochloric acid to the remaining sulphuric acid solution and filtering it.

摘要： A process for preparing methane diphenyl diamine (MDA) or a mixture of methane diphenyl diamine (MDA) and its higher homologues with a controlled isomer distribution using a modified zeolite having 'shape selectivity'. The mixture contains compounds having the following general formula (I): where R represents a hydrogen atom or a C1 to C8 (iso)alkyl group, a C4 to C10 cycloalkyl group or a C6 to C12 aromatic group and n is a whole number greater than or equal to one so as to give a functionality of 2 to 6.

摘要： A process for preparing methane diphenyl diamine (MDA) or a mixture of methane diphenyl diamine (MDA) and its higher homologues with a controlled isomer distribution using a silanised zeolite have 'shape selectivity'. The mixture contains compounds having the following general formula (I): where R represents a hydrogen atom or a C1 to C8 (iso) alkyl group, a C4 to C10 cycloalkyl group or a C6 to C12 aromatic group and n is a whole number greater than or equal to one so as to give a functionality of 2 to 6.
