香蕉水又名天那水,主要成分是二甲苯,挥发性极强易燃易爆有毒,是危险品,主要是因为有较浓的香蕉气味,所以叫香蕉水。 将乙酸乙酯、乙酸了酯、苯、甲苯、丙酮、乙醇、丁醇按一定重量百分组成配制成混合溶剂,称之为香蕉水。纯香蕉水是无色透明易挥发的液体,有较浓的香蕉气味,微溶于水,能溶于各种有机溶剂,易燃,主要用作喷漆的溶剂和稀释剂。 一、配制方法 按重量比,取乙酸正丁酯15%,乙酸乙酯15%,正丁醇10~15%,乙醇10%,丙酮5~10%,苯20%,二甲苯20%,然后将其充分混匀即可制得香蕉水。 二、注意事项 1.香蕉水中各种原料的配比可作适当调整。此外,所用原料也可替换,如乙酸乙酯少就可以用杂酯代替;有时可根据香蕉水的用途不同而选用不同原料。 2.酮类的加入可增加漆膜的光亮度,苯类一般不宜超过40%。 3.在配制香蕉水时,各种原料的含水量要尽量降低到最少程度。 苯不要用,沸点太低,挥发速度太快,容易白化,尤其是湿度较大时,最重要的是危害性和危险性大。 香蕉水,一般称为稀释剂,上世纪20年代进口的硝基漆的稀释剂因有香蕉味的乙酸正丁酯和乙酸乙酯,俗称香蕉水;现在各种漆类的稀释剂的配方不一样,一般的硝基漆的稀释剂的配方参考为乙酸正丁酯20%,乙酸乙酯20%,正丁醇10~15%,乙醇5%,丙酮5~10%,甲苯40%,高级品中另加乙二醇乙醚醋酸酯5-10%,甲基异丁酮10%。苯不要用,沸点太低,挥发速度太快,容易白化,尤其是湿度较大时,最重要的是危害性和危险性大。

甲苯、醋酸丁酯、环己酮、醋酸异戊酯、乙二醇乙醚醋酸酯。
由多种有机溶剂配制而成的无色透明易挥发的液体,微溶于水,能溶于各种有机溶剂,易燃,主要用作喷漆的溶剂和稀释剂。在许多化工产品、涂料、黏合剂的生产过程中也要用到香蕉水做溶剂。
扩展资料:
用途
1、乙酸异戊酯是重要的溶剂,能溶解硝化纤维素、甘油三松香酸酯、乙烯树脂、香豆酮树脂、松香、乳香、达马树脂、山达树脂、蓖麻油等。
在日本,本品80%用作香料,有较强的果实香味,似梨、香蕉、苹果等香味。因此广泛用作各种食用果实香精。在烟用香精、日用化妆香精中也有适量应用。还用于人造丝、染料、人造珍珠、青霉素的提取等方面。
2、用作油脂、橡胶、硝酸纤维素、清漆、鞋油、油墨、防水漆、织物染色处理、药品萃取精制等的溶剂以及香料制造。
3、用作分析试剂,如作溶剂,萃取剂,色谱分析标准物质。还用作食品添加剂。还用于印染、照相业。
4、是制造喷漆溶剂、稀释剂的主要成分之一。
化学性质
1、与低级乙酸酯类相比,不易水解;但在苛性碱存在下,水解生成乙酸和异戊醇。
2、乙酸异戊酯在氮气流中于700℃通过玻璃棉时,分解为3-甲基-1-丁烯及少量的丙酮。
3、将氨和乙酸异戊酯的混合物通过热至490~500℃的氧化铝时,生成乙腈、异戊醇、乙烯和氢等。
4、乙酸异戊酯在乙醚溶液中与碘化镁、四氯化钛生成结晶性的分子化合物。
5、乙酸异戊酯也能发生醇解、氨解、酯交换、还原等一般酯类的共同反应。
储存注意事项
储存于阴凉、通风的库房。远离火种、热源。库温不宜超过37℃。应与氧化剂、酸类、卤素分开存放,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。

Shoe Or Silverware ShinerYou just ran out of shoe shine just when you need it for a job interview. Not to worry. When you’re finished with your breakfast banana, don’t throw out the peel. Remove the stringy material from the inside, then rub the soft inside of the skin all over your shoes. When done, buff it up with a soft cloth or paper towel (More tips on how to shine shoes). The same technique can be used for silverware. Some even claim that it works on leather. Test in on a small area of the leather first, though, just to be on the safe side.
