    • A process for the preparation of aqueous solutions of alkali organosiliconates in which organoalkoxypolysiloxanes of the formula ##EQU1## in which R.sup.1 is an alkyl residue with 1 to 3 carbon atoms, a vinyl residue and/or a phenyl residue,R.sup.2 is an alkyl residue with 1 to 4 carbon atoms,a is a number .ltoreq.2, andx is 1 to 1.25,are reacted with aqueous solutions of sodium hydroxide or potassium hydroxide having a concentration of 0.7 to 0.9 mole/100 g at temperatures .gtoreq.80.degree. C. The liberated alcohol R.sup.2 OH may be distilled and/or the concentration adjusted to the desired value by the addition of water. With the present invention, alkali chloride-free alkali organosiliconate solutions having high concentration can be obtained while avoiding a filtration step.
    • 一种制备碱有机硅酸盐的水溶液的方法,其中式为“IMAGE”的有机烷氧基聚硅氧烷,其中R 1为具有1至3个碳原子的烷基残基,乙烯基残基和/或苯基残基,R2为烷基残基, 1至4个碳原子,a为数2,x为1至1.25,在温度≥80℃下与浓度为0.7至0.9摩尔/ 100g的氢氧化钠或氢氧化钾的水溶液反应 可以将释放的醇R2OH蒸馏和/或通过加入水将浓度调节至所需值。 通过本发明,可以在避免过滤步骤的同时获得高浓度的无碱金属氯化物的有机硅酸盐溶液。
