目前,我所能确定的是: 二者分子式相同,CAS号相同!
自己画的分子式也相同，但就查不到一个确定的说法！

请高手指教？

甲基异丙烯基醚 116-11-0

第三部分：危险性概述回目录
危险性类别：
侵入途径：
健康危害：本品具有刺激作用。
环境危害：
燃爆危险：本品极度易燃，具刺激性。

第四部分：急救措施回目录
皮肤接触：脱去污染的衣着，用流动清水冲洗。
眼睛接触：提起眼睑，用流动清水或生理盐水冲洗。就医。
吸入：脱离现场至空气新鲜处。如呼吸困难，给输氧。就医。
食入：饮足量温水，催吐。就医。

第五部分：消防措施回目录
危险特性：其蒸气与空气可形成爆炸性混合物，遇明火、高热极易燃烧爆炸。与氧化剂能发生强烈反应。其蒸气比空气重，能在较低处扩散到相当远的地方，遇火源会着火回燃。若遇高热，可发生聚合反应，放出大量热量而引起容器破裂和爆炸事故。
有害燃烧产物：一氧化碳、二氧化碳。
灭火方法：消防人员须佩戴防毒面具、穿全身消防服，在上风向灭火。尽可能将容器从火场移至空旷处。喷水保持火场容器冷却，直至灭火结束。处在火场中的容器若已变色或从安全泄压装置中产生声音，必须马上撤离。灭火剂：雾状水、泡沫、干粉、二氧化碳、砂土。用水灭火无效。

第六部分：泄漏应急处理回目录
应急处理：迅速撤离泄漏污染区人员至安全区，并进行隔离，严格限制出入。切断火源。建议应急处理人员戴自给正压式呼吸器，穿防毒服。尽可能切断泄漏源。防止流入下水道、排洪沟等限制性空间。小量泄漏：用活性炭或其它惰性材料吸收。也可以用不燃性分散剂制成的乳液刷洗，洗液稀释后放入废水系统。大量泄漏：构筑围堤或挖坑收容。用泡沫覆盖，降低蒸气灾害。用泵转移至槽车或专用收集器内，回收或运至废物处理场所处置。

第七部分：操作处置与储存回目录
操作注意事项：密闭操作，全面通风。操作人员必须经过专门培训，严格遵守操作规程。建议操作人员佩戴自吸过滤式防毒面具（半面罩），戴化学安全防护眼镜，穿防毒物渗透工作服，戴橡胶耐油手套。远离火种、热源，工作场所严禁吸烟。使用防爆型的通风系统和设备。防止蒸气泄漏到工作场所空气中。避免与氧化剂、酸类接触。搬运时要轻装轻卸，防止包装及容器损坏。配备相应品种和数量的消防器材及泄漏应急处理设备。倒空的容器可能残留有害物。
储存注意事项：通常商品加有阻聚剂。储存于阴凉、通风的库房。远离火种、热源。库温不宜超过28℃。保持容器密封。应与氧化剂、酸类分开存放，切忌混储。采用防爆型照明、通风设施。禁止使用易产生火花的机械设备和工具。储区应备有泄漏应急处理设备和合适的收容材料。
