关于什么是有机 solvent? 有机 solvent 是指一类由organic molecule 为介质 的 solvent。它包括多类物质,如alkanes, alkenes, alcohols, ketones, amines, esters, ethers, ketones 和 aromatic hydrocarbons 等等.
在 industrial production 中,有organicsolvent 通过清洗去污稀释萃取等过程来使用,它们作为中间体也被用在 chemical synthesis 中。常用的 organicsolvents 包括:
Hydrocarbon: 如脂肪族链烷烃
Halogenated hydrocarbons: 如卤代烷
Alcohols: 如甲醇
Ketones: 如丙酮
Ethers:
Others: Like carbon disulfide
Organic solvents' properties:
Volatility and solubility - Organic solvents are often volatile and can easily penetrate the body through inhalation.
Chemical structure - Based on their chemical structures, organic solvents can be divided into several categories with similar toxicities.
Absorption and distribution - After being inhaled or ingested, most organic solvents distribute to fatty tissues in the body such as nerve systems and liver.
The biological transformation of organic compounds is closely related to their toxicity.
Organic compounds are mainly excreted from the body unchanged or as metabolites.
Most organic compounds have short biological half-lives ranging from minutes to days.
Therefore biological accumulation does not significantly affect the toxicity of most organic compounds.
Industrial use of Organic Solvents:
Solvent selection for specific applications is crucial due to varying compatibility with materials being processed.
The choice between different types of filters depends on factors like filtration rate requirements for process efficiency.
Additionally considerations include temperature stability limits required by certain manufacturing processes.
It is important that these filters be regularly inspected and maintained for optimal performance over time.
In cases where chemicals may react with filter materials causing degradation over time it becomes necessary to consider alternative filter options.\
