Optimum selection of methal equipment

The use of methal is not mentioned here.

The advantages and disadvantages of using methacetal equipment are:

Superior physical properties: low boiling point, high vapor pressure, small odor, easy to vaporize and volatilization, do not leave traces after evaporation.

Superior solubility: methal is a two parent type, which has good solubility in both polar and nonpolar, alkanes and aromatics, ethers, ketones and halogenated hydrocarbons, and can be used as phase solvents.

Superior safety: methal poisoning is the lowest type of chemical poisoning, micro toxic grade, from production to the use of the environment does not produce pollution, is a green environmental solvent. In addition to polyol ether, the toxicity of other organic solvents is generally far greater than that of methyl acetal.

Superior Economy: the upstream raw materials of acetal are coal and natural gas. China is a large coal country with abundant resources. Most of the other solvents are upstream oil, and the cost of petroleum is far greater than that of coal. The cost is economic. At the same time, the density of methyl acetal is smaller than that of halogenated hydrocarbons, such as two chloroethane, which is a substitute for halogenated hydrocarbon.

Disadvantages: low boiling point, fast evaporation, flammable, and a little peculiar smell.
