  Butylene glycol  and propylene glycol are common organic compounds. Their main uses are as follows: Butanediol is mainly used in the manufacture of solvents, plastics, coatings, pigments, resins, fibers, etc. It can also be used to make softeners, refrigerant fluids, heat exchange fluids, etc. Propylene glycol is mainly used in the manufacture of coatings, resins, paints, fibers, etc. It can also be used in the manufacture of medicines, spices and food additives. Both butylene glycol and propylene glycol can be used as smoke thickeners in tobacco to make the smoke richer. Butylene glycol and propylene glycol can also be used in the synthesis of dyes and pigments to increase their stability, softness and solubility. Butylene glycol and propylene glycol can be used as one of the raw materials for synthetic resin. The synthetic resin has good flexibility, plasticity and durability.

  Why is Butylene Glycol More Toxic Than Propylene Glycol: Both  butylene glycol  and propylene glycol have certain toxicity. Although they will not cause direct harm to the human body, they can cause irritation and discomfort if they come into contact with the skin or eyes. Butylene glycol is widely used in industry, mainly in the manufacture of polyester resin and polyurethane. Polyester resin is an important engineering plastic that is widely used in the manufacture of automobiles, electrical appliances, building materials, etc. Polyurethane is a multifunctional material with excellent insulation, wear resistance and aging resistance. It is widely used in insulation materials, furniture, sports equipment and other fields. Butylene glycol is highly toxic. If you accidentally eat or inhale butylene glycol, it may cause serious harm to the human body and even be life-threatening. Therefore, when using butylene glycol and propylene glycol, operating procedures must be stri...

  The difference between   butylene glycol   and propylene glycol is as follows: Different uses: Butanediol is mainly used to make solvents, plastics, coatings, pigments, resins, fibers, etc. It can also be used to make softeners, refrigerant fluids, heat exchange fluids, etc. Propylene glycol is mainly used in the manufacture of coatings, resins, paints, fibers, etc. It can also be used in the manufacture of medicines, spices and food additives. Different water solubility: Butanediol has poor water solubility, its solubility in water is only 3.6%. Propylene glycol has better water solubility, and its solubility in water can reach 100%. Different melting points: The melting point of butanediol is relatively low, only -74°C. The melting point of propylene glycol is relatively high, -16.6°C. Differences in Toxicity: Butylene glycol is more toxic than propylene glycol. The LD50 value of butylene glycol is 1.5g/kg, while the LD50 value of propylene glycol is 5.6g/kg.

  What kind of substance is THF? THF  is a chemical reagent of thorium fluoride.   Alias:  tetrahydrofuran , 1.4-epoxybutane, tetramethylene oxide, oxyheterocyclic pentane, monooxypentacyclic, tetrahydroxycyclocene, polytetramethylether glycol, tetramethylene oxide, oxyheterocyclic pentane, monooxyacyclic   CAS: 109-99-9 Molecular formula: C4H8O Molecular weight: 72.11 PSA 9.23000 LogP 0.79680 Merck 9211 Refractive index n20/D 1.40 Miscible Boiling point 65-67 ° C (l In industrial production, sugar aldehyde was first used as raw material. The mixture of sugar aldehyde and steam was introduced into the reactor filled with zinc chromium manganese metal oxide (or palladium) catalyst, and the carbonyl group was removed at 400-420 ℃ to form furan; Then tetrahydrofuran was prepared by hydrogenation of furan at 80-120 ℃ using skeleton nickel as catalyst. The production of 1 ton of tetrahydrofuran by this method requires about 3 tons of polysaccharide aldehyde. With exc...
