The essence in the air fresheners currently on the market usually uses ethanol as a solvent to achieve mutual solubility with propane butane, and use more ethanol to affect the smell of the freshener. After the use of methylal, the solubility of the fragrance can be greatly improved, the amount of ethanol can be reduced, the fragrance of the freshener can be improved, and the emission of VOCs can be reduced. Especially for dry-mist air fresheners, using a small amount of methylal can make the essence and propane miscible with each other, which can better reflect the "dry" of the dry-mist type. Application in ribbon formulation. In the ribbon formula, the polymer polyacrylate solid raw material is mainly used, and F11 is used as the solvent in the original formula. With the ban of Freon, the use of methylal as a solvent will achieve the purpose of good solubility and fast volatility. Use in electronic equipment cleaner formulations. At present, most of the production uses F11 and F113 as the main raw materials. With the ban of Freon, it will also be replaced by methylal. The solvent can be synergistic by mixing a small amount of methylal equipment with ethanol, ester or ketone. These characteristics of methylal make it particularly suitable as an additive in paint and varnish formulations, glues and adhesives, inks and various aerosol products, enabling products to obtain excellent homogeneous phases. Methylal can be used in greases, waxes, nitrocellulose, natural resins, rosin, tall oil, most synthetic resins, polystyrene, vinyl acetate polymers and copolymers, polyesters, acrylates, paraffin Acrylic ester, polyamine resin, epoxy resin, chlorinated rubber, etc. are used for quantitative dissolution. , it can be used as a fuel additive, which has obvious benefits to the combustion performance of the fuel and reduces harmful gas emissions. It can also be used as a substitute for Freon in air-conditioning refrigerants.
