                      乙酸異戊酯氣體檢測管188U ISOPENTYL ACETATE 10-400ppm

                      簡要描述:

                      乙酸異戊酯氣體檢測管188U ISOPENTYL ACETATE 10-400ppm CH3CO2(CH2)2CH(CH3)2 別名:醋酸異戊酯;香蕉油;香蕉水檢測管。色狀: 無色透明液體,較強(qiáng)的新鮮果香,稍甜,有類似熟香蕉、生梨和蘋果樣的氣味。健康危害:蒸氣對(duì)眼及上呼吸道粘膜有刺激性。有麻醉作用接觸后出現(xiàn)咳嗽、胸悶、疲乏、限燒灼感。高濃度時(shí),則有頭暈、發(fā)燒感受。脈速、心悸、頭痛、耳鳴、震顫、惡心、食欲喪失。可引起皮膚干燥、皮炎、濕疹。
