Tetrahydrofurfuryl methacrylate 2455-24-5
Category : Paint and Coatings/Inks and Printing Oil
CAS NO : 2455-24-5 EC NO : 219-529-5 MF : C9H14O3 MW : 170.2057 Specification : 99% min Packing : 25kg，50kg 200kg net drum Product description : What is the chemical of Tetrahydrofurfuryl methacrylate? Appearance:coloress to light yellow liquid Assay： 98% min and 99% min by GC IR Identity: conform to standard HNMR： conform to standard carbon spectrum: conform to standard Water by K. F.:0.5% max or as per the customer’s request Loss on drying:0.5% max. or as per the customer’s request ============================================================================== Usage: Adhesive: used as a crosslinking agent or modifier to enhance bonding performance. Ink/Paint: Improve film-forming, adhesion, and weather resistance. Rubber/plastic: used as a crosslinking agent or modifier to enhance material properties. UV curable materials: participate in photo initiated polymerization reactions as single functional monomers. ============================================================================== Synthesis route: Methacrylate tetrahydrofurfurfuryl ester (also known as THFMA), its core synthetic route is based on the esterification reaction of methacrylic acid and tetrahydrofurfuryl alcohol, mainly divided into two processes: laboratory preparation and industrial production: 1. Classic synthesis route in the laboratory Using acid as a catalyst, prepare by direct esterification method: Core raw materials: Methacrylic acid+tetrahydrofurfuryl alcohol Reaction conditions: Using p-toluenesulfonic acid or sulfuric acid as acid catalysts, the reaction is carried out under reflux conditions, and the water generated by the reaction is removed by azeotropic distillation to push the equilibrium towards esterification Post treatment process: After the reaction is completed, neutralization treatment is carried out to remove the catalyst, and finally the target product is purified by vacuum distillation. 2. Industrial scale synthesis route Industrial production will optimize catalytic systems to enhance selectivity and reduce side reactions. The mainstream processes are: Continuous esterification process: using immobilized lipase catalyst or multiphase acid catalyst for continuous esterification reaction, compared with traditional homogeneous catalysis, has higher product selectivity, simpler post-treatment, and less waste emissions. 3. Other synthesis methods The public information also records another reaction condition scheme: using 4-acetamido-2,6,6-tetramethyl-1-piperidine oxide and dibutyltin oxide as catalysts, in a mixed solvent of 2-methylpentane and cyclohexane, the reaction is carried out at 85-100 ℃ for 12 hours, and the yield of this route can reach 95%. The upstream core raw materials of this substance are clearly tetrahydrofurfuryl alcohol and methyl methacrylate, which can also be prepared by ester exchange reaction between methyl/ethyl methacrylate and tetrahydrofuryl alcohol. Uses : Adhesive: used as a crosslinking agent or modifier to enhance bonding performance. Ink/Paint: Improve film-forming, adhesion, and weather resistance. Rubber/plastic: used as a crosslinking agent or modifier to enhance material properties. UV curable Synonyms : Methacrylic acid tetrahydrofurfuryl ester;tetrahydrofuran-2-ylmethyl 2-methylprop-2-enoate; Molecular Structure :
