Description

Application:

  1. Used as good solvents on a variety of polymers such as polyethylene, polyvinyl chloride, pan, polyamide, etc. It can be used for acrylic fiber and other synthetic fibers of wet spinning, polyurethane synthesis;
  2. Used in the plastic film;
  3. Used for catalysts for chemical reactions;
  4. Used as a gas absorber for the separation and purification of gases in the petrochemical industry.
  5. Used to remove paint; it can also dissolve some of the low solubility of the pigment, so that the characteristics of dyes with dyes;
  6. Used in the pesticide industry. It can be used for the synthesis of iodine amine pyrimidine, doxycycline, cortisone, vitamin B6, antitumor ammonia acid, furosemide fluorouracil, bile dimension he, etc.

Health Hazard:

The acute toxicity of DMF is low by inhalation, ingestion, and skin contact. Contact with liquid DMF may cause eye and skin irritation. DMF is an excellent solvent for many toxic materials that are not ordinarily absorbed and can increase the hazard of these substances by skin contact. Exposure to high concentrations of DMF may lead to liver damage and other systemic effects. Dimethylformamide is listed by IARC in Group 2B (“possible human carcinogen”). It is not classified as a “select carcinogen” according to the criteria of the OSHA Laboratory Standard. No significant reproductive effects have been observed in animal tests. Repeated exposure to DMF may result in damage to the liver, kidneys, and cardiovascular system.
