1,2丙二胺用途普遍可用于選礦劑、金屬鈍化劑、作物保護(hù)劑、燃料油和潤(rùn)滑油添加劑、用于染料、電鍍和分析試劑（汞、銅和銀的檢定），還可用作航空用樹(shù)脂固化劑、橡膠硫化促進(jìn)劑及生產(chǎn)。1,2-丙二胺四乙酸作為抗ai藥丙亞胺的中間體。但目前用量并不大，全國(guó)需求*1千多噸，國(guó)產(chǎn)商品很少，主要是進(jìn)口1,2丙二胺滿(mǎn)足市場(chǎng)需求。根據(jù)它的性能及用途，市場(chǎng)前景還是不錯(cuò)，但市場(chǎng)需求還需培育及開(kāi)發(fā)。1，2-丙二胺應(yīng)密閉貯存,防潮,防熱,與酸類(lèi)物品隔離。安徽巴斯夫1-2丙二胺</p><p
