Description

  1. Product Overview

异丙醇(Isopropanol,分子式 C3H8O,CH3CHOHCH3)是最简单的仲醇,常温下为无色透明、具乙醇与丙酮混合气味的挥发性易燃液体,能与水、乙醇、乙醚、苯、氯仿等多数有机溶剂互溶,与水混溶(形成共沸物,含 87.7 %(质量分数)异丙醇、沸点约 80.4 °C)。微毒,有麻醉性,主要作用于中枢神经系统。

Isopropanol (C3H8O, CH3CHOHCH3) is the simplest secondary alcohol; a colorless, volatile, flammable liquid at room temperature with a mixed ethanol-acetone odour. Miscible with water, ethanol, ether, benzene, chloroform and most organic solvents; miscible with water (forms an azeotrope of 87.7 wt% IPA, bp ~80.4 C). Slightly toxic, narcotic, chiefly acting on the central nervous system.

其主要用途极广:作为有机溶剂用于油墨、涂料、清洗剂(电子/精密清洗、消毒杀菌)、化妆品与医药(外用消毒剂、洗手液、赋形剂);医药与农药中间体;萃取剂、脱蜡剂、防冻液组分;实验室试剂与色谱分析;也是合成丙酮、乙酸异丙酯等的重要原料。性能上兼具醇的极性与良好的溶解力,对亲油性物质溶解力优于乙醇。

Principal uses are very broad: solvent for inks, coatings, cleaners (electronics/precision cleaning, disinfection/sanitization), cosmetics and pharma (topical antiseptic, hand sanitizer, excipient); pharma and agrochemical intermediate; extractant, dewaxing agent, antifreeze component; laboratory reagent and chromatography; also a key feedstock for acetone and isopropyl acetate. Combines alcohol polarity with strong solvency, outperforming ethanol for lipophilic substances.
