咪唑啉水溶性(xing)緩蝕劑

關于咪唑啉水溶(rong)緩蝕劑

咪(mi)唑啉(lin)在原油開采(cai)和(he)煉化(hua)過(guo)程中,是一種性(xing)能優異、應用廣泛(fan)的緩(huan)蝕(shi)劑(ji)。

咪唑(zuo)啉(lin)由長(zhang)碳(tan)鏈脂肪酸與多(duo)乙烯多胺(an)經過(guo)高溫(wen)真空(kong)反應成環,一般結構(gou)式爲(wei),然後(hou)經過季胺化反應生(sheng)成咪唑(zuo)啉衍生物,再(zai)經過增效(xiao)劑(ji)複配(pei)得到成(cheng)品。此緩(huan)蝕劑能(neng)在鋼鐵表(biao)面形(xing)成一層緻(zhi)密的(de)保護膜,一方面(mian)改變金屬表面(mian)的電荷(he)分布(bu)和界面性質,使金(jin)屬表(biao)面(mian)的(de)能量狀态趨(qu)于穩定(ding)化(hua),減低腐蝕反(fan)應;另一方(fang)面由(you)于非極性基團緊密排列(lie)在金(jin)屬表(biao)面形成一(yi)層(ceng)疏水膜,使腐(fu)蝕反應得到(dao)抑(yi)制;同(tong)時它(ta)在金(jin)屬表面(mian)可以改變氫(qing)離子(zi)的氧(yang)化(hua)還原電位,也(ye)可以(yi)絡合溶液(ye)中的(de)某些(xie)氧化劑,減低(di)電位達到緩蝕的(de)目的。

 咪唑(zuo)啉水溶性緩蝕(shi)劑無特殊(shu)的刺激性氣(qi)味(wei),穩定(ding)性好(hao),毒性低,屬(shu)于環(huan)境(jing)友好型(xing)緩蝕(shi)劑。

此緩(huan)蝕劑在(zai)中石(shi)化(hua)、中石油(you)各煉(lian)化(hua)企(qi)業得(de)到大(da)量應用。
