Methyl acrylate can be prepared by debromination of methyl 2,3-dibromopropanoate with zinc. [10] Methyl acrylate is formed in good yield on pyrolysis of methyl lactate in the presence of ethenone (ketene). [11] Methyl lactate is a renewable "green chemical". Another patent [12] describes the dehydration of methyl lactate over zeolites.

Acrylates (IUPAC: prop-2-enoates) are the salts, esters, and conjugate bases of acrylic acid. The acrylate ion is the anion CH 2 =CHCO − 2. Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. These acrylates contain vinyl groups.
Heating the polymer causes depolymerization of the cured MCA, producing gaseous products which are a strong irritant to the lungs and eyes.With regard to occupational exposure to MCA, the National Institute for Occupational Safety and Health recommends workers do not exceed exposures over 2 ppm (8 mg/m 3) over an eight-hour workshift, or over 4 ppm (16 mg/m 3) over a short-term exposure.
Poly(methyl acrylate) (PMA) is a family of organic polymers with the formula (CH 2 CHCO 2 CH 3) n. It is a synthetic acrylate polymer derived from methyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from methyl acrylate and other monomers.
Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic , used as an engineering plastic . PMMA is also known as acrylic , acrylic glass , as well as by the trade names and brands Crylux , Hesalite , Plexiglas , Acrylite , Lucite , and Perspex , among several others ( see below ).
CH 2 =C(CH 3)CN + H 2 SO 4 + H 2 O → CH 2 =C(CH 3)−CONH 2 ·H 2 SO 4 CH 2 =C(CH 3)−CONH 2 ·H 2 SO 4 + CH 3 OH → CH 2 =C(CH 3)COOCH 3 + NH 4 HSO 4. Mitsubishi Gas Chemicals proposed that MAN can be hydrated to methacrylamide without using sulfuric acid and is then esterified to obtain MMA by methylformate. [10] CH 2 =C(CH 3)CN + H 2 O ...
[2] Methoxyacrylates are utilized as agricultural fungicides. [1] Their primary advantage is their potent toxicity against a wide range of fungi, coupled with low toxicity in mammals, making them a vital class of active ingredients. [3] Methoxyacrylates hold significant importance in the field of agricultural fungicides, with a substantial ...
