Solvents, or solvents, are organic liquids that consist of a large number of chemicals that are often used to dissolve or dilute other substances or materials. Solvents are one of the most widely regulated chemical classes, and volatile organic compounds that contribute to lower levels of ozone formation are also regulated as VOC (Volatile Organic Compounds). Reviews We can divide the production methods into two as follows.
a) Traditional methods
b) Biological based methods
In the traditional method, as we all know, solvents are obtained in secondary, tertiary stages by distillation of natural gas and / or oil.
In the biological method, the need for greener sustainable chemicals is achieved by the processing of renewable raw materials. Therefore, in order to produce not only herbal products, but also biological based chemicals, many kinds of waste are used, such as the peels of fruits and ashes of biomass incinerators.
