Bis[2-hydroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]propane and 2-Hydroxy-2-methyl-1-phenyl-propan-1-one（CAS#163702-01-0）
I. Basic Identification Information
Full Chemical Name: 3,4-Epoxycyclohexylmethyl Methacrylate
CAS Number: 163702-01-0
Core Properties: Acrylate reactive monomer containing alicyclic epoxy groups, colorless to slightly yellow transparent liquid at room temperature, density 1.09 g/cm³, boiling point 275°C, flash point 132°C, the core functional monomer for UV photocuring systems and epoxy modified resins
II. Clarified Safety Operation Requirements
Storage Safety: Seal and store in a cool, dry, dark area below 25°C, add a trace amount of polymerization inhibitor for stable storage, keep away from heat sources, open flames and strong oxidizing substances. Avoid long-term storage at high temperature which may cause self-polymerization and gelation of acrylate double bonds
Operation Protection: Wear chemical-resistant nitrile gloves, goggles and activated carbon protective masks during operation, work in a fume hood to prevent liquid splashing from contacting skin and eyes, and avoid massive inhalation of volatile vapors
III. Confirmed Potential Risk Warnings
Skin Irritation Risk: Classified as a moderately irritating acrylate substance. Long-term direct contact may cause skin redness, itching and mild burns, and some sensitive people may develop local allergic reactions
Eye Damage Risk: Direct splashing of the liquid into eyes will cause moderate to severe irritation. Failure to handle it in time may cause corneal damage and temporary vision loss
Inhalation Irritation Risk: High-concentration vapors volatilized at high temperature will strongly irritate the respiratory tract, causing severe cough, sore throat and chest tightness
Self-polymerization Exothermic Risk: When heated above 150°C or in contact with peroxide initiators, a rapid self-polymerization exothermic reaction will occur, which may cause overpressure rupture of the container in severe cases
IV. Emergency Disposal and Supplementary Note
In case of skin contact, immediately rinse with plenty of clean water and soap water for more than 15 minutes. If the liquid accidentally enters eyes, continuously rinse with running water for more than 15 minutes and seek medical attention in time; if inhaled accidentally, immediately move to fresh air, and seek medical attention immediately when breathing discomfort occurs
