Corrosion Control by water‐soluble extracts from leaves of economic plants

Water extracts from leaves of date palm, phoenix dactylifera, henna, Lawsonia inermis, and corn, Zea mays, were tested as corrosion inhibitors for steel, aluminum, copper and brass in acid chloride and sodium hydroxide solutions using weight loss, solution analysis and potential measurements. The inhibition action was found to critically depend on metal type and solution composition. Only, date palm and henna extracts were found highly effective in reducing corrosion rate of steel in acid chloride solutions and aluminum in sodium hydroxide solutions. The inhibition efficiency increased with increasing the concentration of the extract. The inhibition was interpreted in terms of chemisorption of some active ingredients in the leaves according to Temkin isotherm.

东海盆地西南部地质特征与油气分布探讨

本文根据近3×10~4km地震和13口探井及其它地球物理、地质等方面资料,综合分析认为:东海盆地西南部与盆地其它部分在发育演化、构造运动、沉积环境等方面差异甚大。 盆地西南部(杭州湾—冲绳岛断裂以南地区)发育演化经历了断陷—坳陷—隆起—铺盖四个阶段。始新世末期的隆起在研究区演化史上有15～20Ma的沉积间断、剥蚀。这段历程,盆地其它部分未曾经历。其次是区内始新世末期抬升运动,致使始新统及以下老地层受剥蚀,仅始新统最大剥蚀量达1000m,这是盆地内绝无仅有的。第三是第三纪以海相沉积环境为主,特别在始新世,为海侵高潮,海城宽阔达8000km~2,这时盆地东北部正接受陆相沉积。研究区中部(北东向)可能存在超压泥岩及多套生油岩系,应为有利生油气区。研究区可能是盆地最有油气远景地区之一。

Copper phthalocyanine as corrosion inhibitor for ASTM A606-4 steel in 16% hydrochloric acid

A study based on the corrosion inhibition properties of copper phthalocyanine is described. Coverage degrees of copper phthalocyanine (Cu-phcy) on ASTM-A606-4 steel, obtained by weight loss measurements, were fitted to Langmuir, Frumkin, Temkin and Flory–Huggins adsorption isotherms. A better fit to the Langmuir isotherm was obtained. The polarization curves showed that polarization of both the anodic and cathodic reactions were verified for concentrations higher than 10^–4 M, indicating a mixed type action. Only the anodic reactions were polarized for lower concentrations. At high frequencies the Nyquist diagrams showed one capacitive loop attributable to double layer charging and a small one at intermediary frequencies attributable to the faradaic process of hydrogen evolution. The formation of an adsorbed film was characterized by increasing charge transfer resistance values in the low frequency range for increasing inhibitor concentrations. According to the techniques used in this study, copper phthalocyanines showed a high corrosion inhibiting efficiency for all concentrations.     

Gildes model studies of aqueous chemistry. III. Initial SO2-induced atmospheric corrosion of copper

The GILDES computer model, incorporating Stumm's concept of proton- and ligand-promoted dissolution, has been used to simulate the exposure of copper at room temperature to 210 ppb sulfur dioxide and 80% relative humidity. The agreement is good between the calculations and laboratory exposures performed under these exposure conditions. Surface reactions are relatively more important at lower relative humidities and the dominant corrosion products formed are solid state Cu₂SO₃, CuSO₃ and Cu₂U. Free-radical redox processes are important participants and control the relative distribution of Cu(I)- and Cu(H)-containing corrosion products.
