We provide fine quality 1,3-dioxane chemical that is considered either solvent or reagent for chemical processes due to its physical, chemical and toxicological properties. This cyclic reaction product of ethylene glycol and formaldehyde exhibits behavior typical of ethers or acetals as per the conditions. It doesn’t exhibit any unusual toxic effects. It is neither explosive nor spontaneously flammable and has no disagreeable odor.
Under neutral or basic conditions, dioxolane has excellent solvent performance characteristics and should be considered as an attractive substitute for chlorinated solvents, ethers and ketones. It is a colorless liquid and it is miscible with water and most common organic solvents. It is a very good solvent for lacquers and resins and can be used for paint remover and thinner. It is also used in mixtures with glycol or glycol ethers to dissolve difficult-to-dissolve components such as pesticides, herbicides and wood preservatives. It is used as stabilizer for glues, impregnating resins and dispersions.
1,3-dioxolane has been successfully substituted for ethylene dichloride, methylene chloride and THF in specific applications. 1,3-dioxolane may be especially suitable as an economically attractive substitute for THF as the two substances are similar in many respects. Both have similar molecular weights, viscosity, dielectric constants and dipole moments. Dioxolane has higher boiling and flash points but it does not form peroxides as readily as THF.
Dioxane can also substitute for DMSO, DEE and DCM (methylene chloride). It should be considered as a potential substitute for MEK, that is on SARA 313. Dioxane is not a carcinogen and has a low odor threshold. It is also used as a copolymerizing agent with trioxane in the manufacture of polyacetal resins. 1,3-dioxolane has been used with styrene (cationic copolymerization) to make block copolymers.
Dioxane used in adhesives solutions of crystalline polyesters is used in heat-sealable coatings and adhesive applications.The polyesters were formally known to be soluble only in highly toxic solvents such as dioxane and chlorindated solvents. Polyester resins, made from dibasic acids and diols, dibasic anhydrides and diols, and the lower alkyl esters of dibasic acids and diols, are soluble up to 40% by weight of solids in dioxolane.
Dioxane is specifically effective for high molecular weight, crystalline, long-chain linear polyesters. Preferred co solvents for this chemical are THF, acetone, toluene and ethyl acetate. Cross-linking agents are added to polyester resins to impart additional bond strength and chemical and heat resistance.
Some cross-linking agents are isocyanates such as toluene diisocynate, 4,4'-methylene-bis (diphenyl diisocyanate) 1,6-hexamethylene diisocyanate. Uses for these adhesives are heat-seal lids for food products such as butter, yogurt and jelly.They are used in packaging for foods to be microwaved or oven heated and as industrial laminates, such as in sail cloth, cable wrap, flexible circuitry and solar protection film.
Some specified application of 1,3-dioxolane are:
- Reaction solvent for pharmaceutical manufacturing
- Replacement for many chlorinated solvents
- Lithium battery electrolyte solvent component
- Copolymerization agent with trioxane and formaldehyde for manufacturing polyacetal resins
- Copolymerization agent with styrene
- Paint stripper
- Glue stabilizer
