Abstract

The performance of five synthesised phosphonium salts, 4-tolyltriphenyl-phosphonium chloride (TTPPC), 4-phenoltriphenylphosphonium chloride (PTPPC), 4-anilinetriphenylphosphonium bromide (ATPPB), 4-benzyl alcoholtriphenylphosphonium chloride (BATPPC), 4-chlorophenyltriphenylphosphonium bromide (CPTPPB) and two commercially available phosphonium salts, tetraphenylphosphonium bromide (TPPB), and methyltriphenylphosphonium bromide (MTPPB) for the inhibition of zinc corrosion in 1 M HCl at 22°C has been quantified using electrochemical techniques. The inhibitor concentration ranged from 1 × 10^–3 to 1 × 10^–7 mol dm^–3. The degree of corrosion inhibition for zinc in 1 M HCl at 22°C was found to be in the order: CPTPPB > TTPPC > TPPB > PTPPC > BATPPC > MTPPB > ATPPB.

Ph盐抑制盐酸中锌腐蚀的电化学研究

摘要

五个合成phospho盐，4-甲苯基三苯基氯化chloride（TTPPC），4-苯酚三苯基氯化chloride（PTPPC），4-苯胺三苯基溴化（（ATPPB），4-苄基醇三苯基氯化chloride（BATPPC），4-氯苯基三苯基溴化（（CPTPPB）的性能已经使用电化学技术对在22°C下1 M HCl中抑制锌腐蚀的两种市售phospho盐，四苯基溴化phosph（TPPB）和甲基三苯基溴化（（MTPPB）进行了定量。抑制剂的浓度范围从1×10 ^–3到1×10 ^–7 mol dm ^–3。发现在22°C下1 M HCl中锌的腐蚀抑制程度依次为：CPTPPB> TTPPC> TPPB> PTPPC> BATPPC> MTPPB> ATPPB。
