丙酮是重要的有機(jī)合成原料，用于生產(chǎn)環(huán)氧樹脂，聚碳酸酯，有機(jī)玻璃，醫(yī)藥，農(nóng)藥等。亦是良好溶劑，用于涂料、黏結(jié)劑、鋼瓶乙炔等。也用作稀釋劑，清洗劑，萃取劑。還是制造醋酐、雙丙酮醇、氯仿、碘仿、環(huán)氧樹脂、聚異戊二烯橡膠、甲基丙烯酸甲酯等的重要原料。在無煙火藥、賽璐珞、醋酸纖維、噴漆等工業(yè)中用作溶劑。在油脂等工業(yè)中用作提取劑。
用于制取有機(jī)玻璃單體、雙酚A、二丙酮醇、己二醇、甲基異丁基酮、甲基異丁基甲醇、佛爾酮、異佛爾酮、氯仿、碘仿等重要有機(jī)化工原料。在涂料、醋酸纖維紡絲過程、鋼瓶貯存乙炔、煉油工業(yè)脫蠟等方面用作優(yōu)良的溶 劑。
