  The invention comprises the triamines <;FORM:0908213/IV (b)/1>; wherein lower alkylene is one containing up to 7 carbon atoms, R1 is the cyclic portion of a saturated or unsaturated ionone or irone or is the 2-Me-5-isopropyl-cyclopent[en-(1)]yl radical (the significance of the square bracket is explained). R2, R3 are individually alkyl radicals of up to 7 C. atoms, or together with the N. atom to which they are attached, a 5 or 6-membered heterocyclic radical, and R4 is H or alkyl radical of up to 7 C. atoms and their salts. Suitable cyclic values for the terminal disubstituted-amino radical are morpholyl, piperidyl and pyrollidyl. The triamines are obtained by reductive condensation, with hydrogen, of a carbonyl compound <;FORM:0908213/IV (b)/2>; with a triamine <;FORM:0908213/IV (b)/3>; and, if desired, N-alkylating the product and/or transforming it into a salt. Acid salts are formed by reaction with hydrohalides e.g. hydrochlorides and hydrobromides, sulphates, nitrates, phosphates, arylsulphonates e.g. benzene- and toluene-sulphonates, tartrates, citrates, ascorbates, malates and oxalates. The salts can be converted to the free base by treating with e.g. sodium hydroxide from which quaternary salts can be obtained by reaction with alkyl halides e.g. methyl, ethyl and butyl chloride, methyl and propyl bromide, and ethyl iodide, alkyl sulphates e.g. methyl and ethyl sulphate, alkyl nitrates e.g. ethyl nitrate, aralkyl halides e.g. benzyl chloride and bromide, and aralkyl sulphates e.g. phenethyl sulphate. The preparation of N-(3-di Me amino propyl)propanediamine1,3 and N-(4-di Me amino butyl)propanediamine-1,3 from acrylonitrile and the corresponding amine via the nitriles is described.

  该发明涉及三胺化合物<;FORM:0908213/IV (b)/1>;，其中较低的烷基包含最多7个碳原子，R1是饱和或不饱和离子酮或离子烯的环状部分，或者是2-Me-5-异丙基-环戊烯[1]基基团（方括号的意义已解释）。R2，R3分别是最多7个碳原子的烷基基团，或者与它们附着的N原子一起形成5或6元杂环基团，R4是最多7个碳原子的H或烷基基团及其盐。适合末端二取代氨基基团的环状值为吗啡啶，哌啶和吡咯啉。通过与三胺<;FORM:0908213/IV (b)/3>;进行还原缩合反应，使用氢气，可以获得三胺化合物，并且如果需要，可以将其烷基化和/或转化为盐。酸盐可以通过与氢卤酸（例如氢氯酸和氢溴酸）、硫酸盐、硝酸盐、磷酸盐、芳基磺酸盐（例如苯磺酸盐和甲苯磺酸盐）、酒石酸盐、柠檬酸盐、抗坏血酸盐、苹果酸盐和草酸盐反应形成。盐可以通过处理例如氢氧化钠等的碱来转化为自由碱，从而可以通过与烷基卤化物（例如氯化甲基、乙基和丁基，溴化甲基和丙基以及碘化乙基）、烷基硫酸盐（例如甲基和乙基硫酸盐）、烷基硝酸酯（例如硝酸乙基）、芳基烷基卤化物（例如苄氯和溴化苄）以及芳基烷基磺酸盐（例如苯乙基磺酸盐）反应获得季铵盐。描述了从丙烯腈和相应胺经过腈的中间体制备N-(3-二甲氨基丙基)丙二胺1,3和N-(4-二甲氨基丁基)丙二胺1,3的方法。
