Kemikali Properties:

Methyl 2-methyl-2-propenoate ni o ni ohun acrid, tokun wònyí. Ninu ijabọ miiran agbo yii ni a royin lati ni didasilẹ, oorun eso.Methyl methacrylate jẹ methyl ester ti methacrylic acid. O jẹ omi ti ko ni awọ, ti o yipada pẹlu õrùn eso ti o ni õrùn. O ni titẹ oru giga ti o ga julọ (4 kPa ni 20 ° C), solubility omi iwọntunwọnsi (15.8 g / lita), ati kekere log octanol / olùsọdipúpọ ipin omi (Kow = 1.38). Methyl methacrylate jẹ deede 99.9% mimọ ati pe o ni awọn oye kekere ti inhibitor lati fa idaduro polymerization.

Ohun elo:
