The comparison between ethyl ester and dichloromethane
The second is ethyl ester and dichloromethane, both of which are commonly used solvents in the chemical industry. Their properties are different, and their uses are also different.

Ethyl ester has a fragrant and volatile taste. The color is clear and can be mixed with organic solvents such as alcohols and ethers. Its boiling point is suitable, about 70 to 7 degrees. It is flammable in case of fire, but it is slightly toxic and less harmful to the human body. In the field of chemical industry, it is often a solvent prepared by fragrances, paints, inks, etc. Because of its fragrant and volatile taste, it can make products dry quickly and leave a fragrance.

Dichloromethane, colorless and sweet. Its density is heavier than water, and it is also volatile. The boiling point is slightly lower, about 40 degrees, refractory, and better than ethyl ester in fire resistance. However, it is more toxic than ethyl ester, and long-term exposure to its gas is harmful to human nerves, liver, etc. In the chemical industry, it is often an extractant of oils, resins, rubber, etc., because of its strong solubility to organic compounds.

Try to compare the solubility. Ethyl ester dissolves well in polar organic compounds, such as some alcohol-soluble resins; while dichloromethane dissolves particularly well in non-polar and weakly polar organic compounds, such as oils, paraffin, etc.

In terms of safety. Ethyl ester is flammable, and it is necessary to be careful when using it in areas with fire risk. Although dichloromethane is refractory, its toxicity cannot be ignored. It needs to be well ventilated to protect people's health.

Both have their own strengths. Users should weigh the advantages and disadvantages according to actual needs, and choose them to achieve the good efficiency of chemical industry and ensure the safety of production.
