Under normal temperature and pressure, methanol is colorless, transparent, easy to flow, volatile and combustible liquid. Methanol is toxic, and the maximum allowable concentration of methanol in the air is 0.05mg/l. It is mainly used to produce formaldehyde, synthetic fiber, synthetic resin, medicine, pesticide, dye, etc. it is also an excellent fuel and one of the basic organic chemical raw materials. Packing: plastic barrel (or truck trough transportation)
