97-88-1 Usage
Description
Butyl methacrylate (BMA) is the organic compound with the formula C4H9O2CC(CH3)=CH2. A colorless liquid, it is a common monomer for the preparation of methacrylate polymers. It is typically polymerized under free-radical conditions.Butyl methacrylate is a versatile, plasticizing methacrylate monomer that acts as an important building block in many copolymer compositions. Serving as a base for acrylic resins, BMA provides exceptional weather resistance, high gloss, color retention, and durability. BMA contributes more intermediate glass transition and hardness values, with a glass transition temperature (Tg) of 20 °C.

General Description
A clear colorless liquid. Flash point 130°F. Less dense (7.5 lb / gal) than water and insoluble in water. Hence floats on water. Vapors heavier than air. Used to make resins adhesives, and oil additives.
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.

Manganese, the third most abundant transition-metal element after iron and titanium, has recently been demonstrated to be an effective homogeneous catalyst in numerous reactions. Herein, the preparation of silica-supported MnII sites is reported using Surface Organometallic Chemistry (SOMC), combined with tailored thermolytic molecular precursors approach based on Mn2[OSi(OtBu)3]4 and Mn{N(SiMe3)2}2?THF. These supported MnII sites, free of organic ligands, efficiently catalyze numerous reactions: hydroboration and hydrosilylation of ketones and aldehydes as well as the transesterification of industrially relevant substrates.

The present invention relates to a preparation method of methacrylic acid ester. The preparation method of methacrylic acid ester comprises the steps of: a) preparing methacrylic ester by having an ester exchange reaction of alcohol and alkyl methacrylic acid ester in presence of an ester exchange catalyst and a polymerization inhibitor; and b) removing the catalyst by adding methanol and water after the ester exchange reaction.
