text: in diluted acetic acid used in rubber plant,how can i get 100% pure acid? acetic acid used for coagulated natural latex and after few days it is diluted with foam colour brown. though we mixed chemicals with natural latex in our compounding section. after latex go through the acid bath the remaining water and chemicals must retain in acid tray, thus in which way we can purify the acid up to 99%. you can contact any chemical supply company and order glacial acetic acid. flinn scientific supply is a good source as they pay the shipping for hazardous materials. caution, glacial acetic burns..trust me.
