Description

前記一般式(１)で表わされる本発明のカチオン界面活性剤は、アルカノールアミン又は１級アミノ基を有するポリアミンを出発物質として、この分子中の水酸基又は１級アミノ基を先に挙げた脂肪酸又はその脂肪酸クロライド若しくはその脂肪酸ブロマイドでエステル化又はアミド化した後、アミノ基を４級化又は中和することにより製造することができる。但し、この場合、出発物質及び／又は４級化剤として、シクロヘキシル基を有する化合物を用いる必要がある。 Cationic surfactants of the present invention represented by the general formula (1) is a polyamine having alkanolamine or a primary amino group as a starting material, fatty acids mentioned a hydroxyl group or primary amino group in the molecule previously or After esterification or amidation with the fatty acid chloride or the fatty acid bromide, it can be produced by quaternizing or neutralizing the amino group. However, in this case, it is necessary to use a compound having a cyclohexyl group as a starting material and / or a quaternizing agent.

製造例２：
ジエチレントリアミン１０３ｇに椰子油脂肪酸メチルエステル４４０ｇを加え、生成するメタノールを除きながら１２０〜１４０℃で３時間反応させた。この後、反応温度１００℃でエチレンオキサイド４４ｇを反応させて、アミンアミドを得た。このアミンアミドと塩化シクロヘキシル５１ｇを８０℃で１５時間反応させて４級化を行い、本発明品８を得た。同様の方法で、椰子油脂肪酸に代えてパーム油脂肪酸又は大豆油脂肪酸を用いて、本発明品９及び１０を得た。
なお、このようにして得られた本発明品１〜１０及び比較品１〜３の構造を表１に示す。 Production Example 2:
Coconut oil fatty acid methyl ester (440 g) was added to diethylenetriamine (103 g), and the mixture was reacted at 120 to 140 ° C. for 3 hours while removing generated methanol. Thereafter, 44 g of ethylene oxide was reacted at a reaction temperature of 100 ° C. to obtain an amine amide. This amine amide and 51 g of cyclohexyl chloride were reacted at 80 ° C. for 15 hours to perform quaternization, whereby a product 8 of the present invention was obtained. In the same manner, products 9 and 10 of the present invention were obtained by using palm oil fatty acids or soybean oil fatty acids instead of coconut oil fatty acids.
Incidentally, showing the structure of the present invention product 1 to 10 and comparative products 1-3 obtained in earthenware pots this good in Table 1.

上記の本発明品１〜１０及び比較品１〜３のカチオン界面活性剤について以下に示す各種の試験法によって柔軟性等の評価を行なった。
(i) 試験１：生分解性試験
本発明品１〜８又は比較品１〜３の０．１％水溶液についてＪＩＳＫ０１０２の方法に従い、生分解性の試験を行った。その結果を表２に示す。なお、ＢＯＤは生物化学的酸素消費量であって、水中の好気性微生物によって消費される溶存酸素の量であり、ＢＯＤの値の大きいものほど生分解性が高いことを示す。
It was evaluated Therefore such flexibility in a variety of the following test methods for the above products of the present invention 1 to 10 and Comparative products 1 to 3 of the cationic surfactant.
(i) Test 1: Biodegradability test A 0.1% aqueous solution of each of the inventive products 1 to 8 or comparative products 1 to 3 was subjected to a biodegradability test according to the method of JIS K0102. Table 2 shows the results. In addition, BOD is biochemical oxygen consumption, and is the amount of dissolved oxygen consumed by aerobic microorganisms in water. A larger BOD value indicates higher biodegradability.
