Description
По -известному способу получени хлористоводородного диацетил-морфина (героина) основание раствор етс в органических растворител х, как, например , спирт или бензол, и к раствору прибавл ют необходимое количество хлористого водорода, а затем выдел ют хлоргидрат прибавлением серного эфира.In the well-known method of producing hydrochloric diacetyl-morphine (heroin), the base is dissolved in organic solvents, such as alcohol or benzene, and the required amount of hydrogen chloride is added to the solution, and then the hydrochloride is isolated by the addition of sulfuric ether.
Получение хлоргидрата по этому способу имеет следующие недостатки: соль неполностью выпадает в виде смолообразной массы, котора через некоторое врем закристаллизовываетс ; исходное основание должно быть безусловно чистое и не давать окрашенного раствора, иначе окраска увлекаетс 1выпадающей смолообразной Л1ассой и соль получаетс окрашенной; регенераци растворителей спирта и эфира затруднительна;необходимоупотребл ть абсолютный спирт и эфир, и происходит частичное омыление-образование моноацетил-морфина, в особенности при сгущении маточных растворов.The preparation of hydrochloride by this method has the following disadvantages: the salt does not fully fall out in the form of a resinous mass, which crystallizes over time; the original base must be unconditionally pure and not give a colored solution, otherwise the color is entrained by the falling resinous resin and the salt is colored; regeneration of alcohol and ether solvents is difficult; absolute alcohol and ether must be used, and partial saponification-formation of monoacetyl-morphine occurs, especially when the mother liquors are thickened.
По предлагаемому же способу средою , в которой идет солеобразование, беретс сухой уксусный эфир, а хлористый водород прибавл етс в виде крепкого (концентрированного) раствора в абсолютном спирту.According to the proposed method, dry acetic ether is added to the medium in which the salt formation occurs, and hydrogen chloride is added as a strong (concentrated) solution in absolute alcohol.
Хлористоводородна соль выпадает сразу в хорошем кристаллическом виде; соль получаетс совершенно белой и из окрашенных растворов, так что нет надобности исходить из совершенно чистого основани ; регенераци растворител - уксусного этилового эфира не представл ет никаких затруднений (сушка хлористым кальцием ) и по сгущении маточных растворов не получаетс продуктов омылени -моноацетил-морфина .The hydrochloride salt precipitates immediately in good crystalline form; salt is obtained completely white and from colored solutions, so that there is no need to proceed from a completely clean base; regeneration of the solvent - ethyl acetate does not present any difficulties (drying with calcium chloride) and the mono acetyl morphine saponification products are not obtained by thickening the mother liquors.
Пример. 1 кг пергкристаллизованного основани раствор ют вExample. 1 kg of percrystallized base is dissolved in
3800 е уксусно-этилового эфира, и раствор охлаждают водой при сильном помешивании. Когда температура раствора понижаетс до 30°, постепенно прибавл ют точно отвешенное, необходимое: по расчету количество абсолютного спирта, насыщенного 36-37% хлористым водородом. Через короткое врем начинает выпадать хлоргидрат, в который переходит и та часть основани , котора выпала из раствора при охлаждении.3800 e of ethyl acetate, and the solution is cooled with water with vigorous stirring. When the temperature of the solution drops to 30 °, gradually weighed, necessary, are gradually added: by calculation, the amount of absolute alcohol saturated with 36-37% hydrogen chloride. After a short time, the hydrochloride begins to precipitate, into which that part of the base that precipitates out of solution upon cooling.
Сразу выпадает хлоргидрата 93% от теории, а остальной получаетс поHydrochloride immediately falls 93% of the theory, and the rest is obtained by
сгущении маточного раствора. Выход количественный.condensation of the mother liquor. The output is quantitative.
