General Description:
Butyl methacrylate is a clear, colorless liquid with an ester-like odor. It has a flash point of 130°F and is less dense than water, making it insoluble in water and causing it to float on water. Its vapors are heavier than air. It is used to make resins, adhesives, and oil additives.
Production Methods
n-Butyl methacrylate is produced by the reaction of
methacrylic acid or methyl methacrylate with butanol .
Air & Water Reactions
Flammable. Sensitive to moisture. Insoluble in water.
Reactivity Profile
Butyl methacrylate reacts exothermically with acids. Reacts with oxidizing agents. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat is generated with caustic solutions. Generates flammable hydrogen with alkali metals and hydrides. Polymerizes easily .
Health Hazard
Inhalation may cause nausea because of offensive odor. Contact with liquid causes irritation of eyes and mild irritation of skin. Ingestion causes irritation of mouth and stomach.
Fire Hazard
Behavior in Fire: Containers may explode due to polymerization.
Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: May occur upon exposure to heat; Inhibitor of Polymerization: 9-15 ppm monomethyl ether of hydroquinone; 90-120 ppm hydroquinone.
Safety Profile
Moderately toxic by
intraperitoneal route. Mddly toxic by
ingestion, inhalation, and skin contact. An
experimental teratogen. Experimental
reproductive effects. A skin irritant.
Flammable liquid when exposed to heat or
flame. Explosive in the form of vapor when exposed to heat or flame. Violent
polymerization can be caused by heat,
moisture, oxidizers. To fight fire, use foam,
dry chemical, CO2. When heated to
decomposition it emits acrid smoke and
irritating fumes.
Potential Exposure
Forms an explosive mixture with air.
Unless inhibitor is maintained at the proper level, oxidizers,
heat, ultraviolet light, contamination, or moisture may
cause polymerization. May accumulate static electrical
charges and cause ignition of its vapors.

Check Digit Verification of cas no
The CAS Registry Mumber 97-88-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 97-88:
(4*9)+(3*7)+(2*8)+(1*8)=81
81 % 10 = 1
So 97-88-1 is a valid CAS Registry Number.

supporting information, p. 10941 - 10945 (2019/07/17)
A synergistic catalytic method combining photoredox catalysis, hydrogen-atom transfer, and proton-reduction catalysis for the dehydrogenative silylation of alkenes was developed. With this approach, a highly concise route to substituted allylsilanes has been achieved under very mild reaction conditions without using oxidants. This transformation features good to excellent yields, operational simplicity, and high atom economy. Based on control experiments, a possible reaction mechanism is proposed.
