CORROSION RESEARCH ROUND‐UP Available to Purchase

GERMANY Inhibitors in oil refining. Anodic inhibitors of practical importance are chromates and nitrites, especially with water of low oxygen content. Cathodic inhibitors are useful when hard water is to be treated, and glassy phosphates and calcium bicarbonate have rendered useful service. Of the organic inhibitors, sodium benzoate and organic amines are promising. It is, however, considered wiser not to use inhibitors if they are unsuitable or offer insufficient protection.—(P. W. Sherwood, Werkstoffe & Korrosion, 1955, 6, 2–6.)
