Abstract
The alkali metal salts, according to their usual preparation, have a ph too high for injection in 20% solution (the usual amount for anesthetic use is 6-8 g solid), so the solutions are prepared by hydrolysis of α -butyrolactone (I) with slightly less than the theoretical amount of alkaline hydroxide to obtain a ph solution between 7.2 and 7.7. To do this 273 g are placed. Of pure i (n20d 1.436, d0o 1.14441, 1.1286 d180, d204 1.125, b760 206º, 81º b11) in a graduated flask (2 1.) and add double-distilled pyrogenic water (1.5 1.); after stirring to mix, 120 g are added. Of pure naoh. When this has dissolved, the flask is cooled, diluted to the mark, and allowed to stand for 48 hours until the ph is 7.7. In the case (10 1.) the solution is prepared similarly from 1,365 kg. Of i and 841 g. Of koh, obtaining a ph of 7.5. (Machine-translation by Google Translate, not legally binding)
