Patient's question:
The yellow water extracted from Ephedra. Can toluene be used to extract with xylene together? What kind of assistance you need: wondering if the water extracted from Ephedra can be used with toluene and xylene for co-extraction.Doctor's answer:
According to the different positions of the two methyl groups on the six-carbon ring, it can be divided into three types: para-xylene, ortho-xylene, and meta-xylene. It is an unsaturated hydrocarbon organic compound.Guidance: Xylene is a colorless and transparent liquid; it is a mixture of the ortho, meta, and para isomers; it has a distinctive odor; it is flammable. It can be freely mixed with ethanol, chloroform, or ether, but it is insoluble in water. The boiling range is 137–140°C. Xylene is a colorless and transparent liquid.
Survival care: It is generally a mixture of para-xylene, ortho-xylene, meta-xylene, and ethylbenzene. The grade is usually the superior and first-class products with a boiling range of 3°C and 5°C.
