物化性质

外观与性状:
无色液体
密度:
0.943
熔点:
-48ºC
沸点:
100ºC
闪点:
8ºC
水溶解性:
15.9 g/L (20℃)
折射率:
1.413-1.415
存储条件/存储方法:
库房通风低温干燥,与氧化剂、酸类分开存放,不宜久储,以防聚合
稳定性相关:

1.易挥发,易燃,与空气形成爆炸性混合物,溶于乙醇、乙醚、丙酮等多种有机溶剂,微溶于乙二醇和水。受光、热和催化作用易聚合,也可与其他单体共聚,由于存在双键和羧酸基团,还易进行加成、卤化、亲核取代核酯交换反应。易聚合。通常加入10-5氢醌单甲醚作阻聚剂。

2.本品毒性较小。大鼠经口LD50为9400mg/kg。吸入致死浓度Lc5015.33g/m3,作业最高容许浓度为410mg/m3。但其嗅阈为130~250mg/m3,当其浓度尚未达产生毒性之前,其强烈臭味已使人难忍。人体皮肤接触甲基丙烯酸甲酯,只有极少数人会出现红疹。

3.由于生产甲基丙烯酸甲酯的原料氰化钠和中间体氰化氢剧毒,生产装置必须严格保证设备密闭,并保持良好通风,操作人员应有严格的防护措施,配备必要的防护装具。发现中毒现象应立即移至空气新鲜处及时抢救。

2.对环境的影响:
一、健康危害
侵入途径:吸入、食入。
健康危害:人对本品气味感觉阈浓度为85mg/m3 ,刺激作用阈浓度(暴露1分钟)为285mg/m3。中毒表现为乏力、恶心、反复呕吐、头痛、头晕、胸闷、伴有短暂的意识消失、中性白细胞增多症。慢性中毒:神经系统受损的综合症状占主要地位,个别可发生中毒性脑病。可引起轻度皮炎和结膜炎。接触时间长可致麻醉作用。
二、毒理学资料及环境行为
毒性:为麻醉剂,麻醉浓度和致死浓度几乎相同,有弱的刺激作用。
  急性毒性:LD507872mg/kg(大鼠经口);LC503750ppm(大鼠吸入);人吸入725ppm,最小致死浓度;人吸入62ppm×20~90分钟,粘膜刺激;人吸入12.5~25ppm×20~90分钟,头晕,恶心,意识障碍。
亚急性和慢性毒性:狗吸入46800ppm×1.5小时/日×8日,绝对致死浓度,肝、肾有损害。
  致突变性:微粒体致突变:鼠伤寒沙门氏菌34mmol/L。
  生殖毒性:大鼠吸入最低中毒浓度(TCL0):109g/kg(孕6~15天用药),致胚胎毒性,对肌肉骨骼系统有影响。
危险特性:遇明火、高热或与氧化剂接触,有引起燃烧爆炸的危险。若遇高热,可能发生聚合反应,出现大量放热现象,引起容器破裂和爆炸事故。其蒸气比空气重,能在较低处扩散到相当远的地方,遇明火会引着回燃。
  燃烧(分解)产物:一氧化碳、二氧化碳。

前苏联(1975)水体中有害有机物的最大允许浓度0.01mg/L
 嗅觉阈浓度0.21ppm

6.应急处理处置方法:


一、泄漏应急处理
  切断火源。戴自给式呼吸器,穿一般消防防护服。在确保安全情况下堵漏。喷水雾可减少蒸发。用砂土、蛭石或其它惰性材料吸收,然后运至空旷的地方掩埋、蒸发、或焚烧。或用不燃性分散剂制成的乳液刷洗,经稀释的洗液放入废水系统。如大量泄漏,利用围堤收容,然后收集、转移、回收或无害处理后废弃。
二、防护措施
  呼吸系统防护:空气中浓度较高时,建议佩戴防毒面具。
  眼睛防护:戴化学安全防护眼镜。
  防护服:穿防静电工作服。
  手防护:必要时戴防护手套。
  其它:工作现场严禁吸烟。工作后,淋浴更衣。注意个人清洁卫生。
三、急救措施
  皮肤接触:脱去污染的衣着,用肥皂水及清水彻底冲洗。
  眼睛接触:立即翻开上下眼睑,用流动清水冲洗15分钟。就医。
  吸入:脱离现场至空气新鲜处。呼吸困难时给输氧。呼吸停止时,立即进行人工呼吸。
  食入:误服者给饮足量温水,催吐,就医。
  灭火方法:雾状水、泡沫、二氧化碳、干粉、砂土。
