問題:最近我們医务室由專卖公司买来一批95%的酒精,將它配成75%,作外科消毒用,当加水稀釋时,变成乳白色渾濁狀态,請問这种渾濁物是什么?这种酒精是否加有甲醇?是否可以供配内服药用(作溶媒)?是否有内用酒精(配酊剂等用)与外用酒精(消毒等用)之分,如何区别? 答:酒精一般由醱酵酒經蒸溜后制成,而醱酵酒内常含有少量杂醇油,其成分有丙醇、丁醇及異戊醇等。此項醇的分子量均較乙醇大,因此它們在水中的溶解度亦逐漸減小。低級醇如甲醇、乙醇及丙醇,均可与任意量的水混和成均匀液体;而丁醇与異戊醇等較高級醇,由于在水中溶解度較小,当加水稀釋时,即产生白色浑濁;另外如酒精中含有树脂类物 Question: Recently, our clinic purchased a batch of 95% alcohol from a monopoly company, and it was formulated as 75% for surgical disinfection. When diluted with water, it turned into a milky white turbid state. What is this turbid substance? Is this alcohol supplemented with methanol? Can it be used for medicinal purposes (as a solvent)? Is there a difference between alcohol for internal use (for use with expectorants, etc.) and rubbing alcohol (for disinfection)? How is the difference? The fermented fermented wine is made by steaming, and the fermented fermented wine often contains a small amount of fusel oil. Its components include propanol, butanol, and isoamyl alcohol. The molecular weight of this alcohol is greater than that of ethanol, so their solubility in water also gradually decreases. Lower alcohols such as methanol, ethanol and propanol can be mixed with any amount of water into a homogeneous liquid; but higher alcohols such as butanol and isoamyl alcohol, due to their lower solubility in water, when diluted with water, produce white defects. Turbidity; In addition, such as alcohol contains resin
