Description

Do 1 1 tříhrdlé sulfonační banky opatřené míchadlem , vnitřním teploměrem, zpětným chladičem a kapací nálevkou se předloží 139 g vodného roztoku dimetylaminu (32,4 % hm). Přidá se 170,4 g vody a za ohlazení solankou se podchladí na cca 0 °C. Za intenzivního s139 g of an aqueous solution of dimethylamine (32.4% by weight) was charged to a 1 L three-necked sulfonation flask equipped with a stirrer, an internal thermometer, a reflux condenser and a dropping funnel. 170.4 g of water are added and cooled to about 0 ° C with cooling with brine. For intense p

ohlazení a míchání se z kapačky regulovaně dávkuje epichlorhydrin tak, aby reakční teplota v banoe se držela pod +5 °C (5 °C maximum), Vydávkování 92*5 g epichlorhydrinu trvá cca 1 hod. Od konce přídavku posledního množství epichlorhydrinu se míchá dalších 10 minut, načež se z kapačky během 2 hodin nadávkuje 121 g dimetylsulfátu. Teplota se během přidávkování dimety lsuftlátu udržuje v rozmezí 0 až 10 °C (+10 °C maximum). Po vydávkování dimety lsulfátu se teplota zvýší na 50 °C a při zmíněné teplotě se doreaguje další 1 hod. Výtěžek činí 522 g vodného neutrálního roztoku (pH 6) s 50% obsahem účinné látky, tj. 2-hydroxy-3-chlorpropy1-trimetylamoniumme t o sulfátu.epichlorohydrin is controlled in a controlled manner from the dropper, so that the reaction temperature in the banane is kept below + 5 ° C (5 ° C maximum), dispensing 92 * 5 g of epichlorohydrin takes about 1 hour. After 10 minutes, 121 g of dimethyl sulfate was metered from the dropper over 2 hours. The temperature is maintained between 0 and 10 ° C (+ 10 ° C maximum) during the addition of the dimethisulfate dimer. After dispensing of dimethyl sulphate, the temperature is raised to 50 ° C and reacted at this temperature for an additional 1 hour. The yield is 522 g of an aqueous neutral solution (pH 6) with 50% active substance, ie 2-hydroxy-3-chloropropyl to sulfate.

Příklad 2Example 2

Do 0,5 1 sulfonační banky opatřené KPG míchadlem, kapačkou a teploměrem se předloží 36,5 S dieiylaminu, zředí l46 ml vody.A 0.5 L sulfonation flask equipped with a KPG stirrer, dropper and thermometer was charged with 36.5 S of dieiylamine, diluted with 146 mL of water.

Za stálého míchání a mírného chlazení se během l/2 hodiny přikape 46,25 g epichlorhydrinu tak, aby teplota se držela v rozmezí 10 až 20 °C. Od ukončení přídavku epichlorhydrinu se při stejné teplotě míchá dalších 10 minut, načež se započne dávkovat dimety1sulfát. Teplota během dávkování dimetylsulfátu se udržuje za mírného přichlazování v rozmezí 10 až 20 °C, Vydávkování 62 g dimetylsulfátu trvá oca 1 hodinu. Teplota se zvedne na 50 °C, načež se při zmíněné teplotě doreaguje další 1 hodinu. Výtěžek činí 290 g čirého světlého nažloutlého roztoku s 5θ$ obsahem akt.l., pHs6.While stirring and gentle cooling, 46.25 g of epichlorohydrin are added dropwise over 1/2 hours, maintaining the temperature between 10 and 20 ° C. After the addition of epichlorohydrin was complete, the mixture was stirred at the same temperature for a further 10 minutes, and then dimethyl sulfate was started. The temperature during the dimethylsulfate dosing is maintained under moderate cooling in the range of 10-20 ° C. The dispensing of 62 g of dimethylsulfate lasts for 1 hour. The temperature is raised to 50 ° C and then reacted at this temperature for a further 1 hour. The yield was 290 g of a clear, light yellowish solution having an active substance content of 5%, pH6.
