WebThe effect of impurities, formic acid, water, and formaldehyde in methanol on the stress corrosion susceptibility of low carbon steel sheet was investigated by the constant strain rate test. Bent specimens of low carbon steel showed high susceptibility to stress corrosion in methanol containing 0.01-0.02 wt% formic acid and 0.05-0.2 wt% water. WebAug 15, 2006 · Aldehyde acetals and ketone ketals were reductively aminated in one pot with aromatic amines to give the corresponding amines in methanol or aqueous methanol in good to high yields. This direct method might be important because acetals and ketals are used as a popular protecting group for aldehyde and ketones.
WebStress corrosion cracking (SCC) is the cracking induced from the combined influence of tensile stress and a corrosive environment. The impact of SCC on a material usually falls between dry cracking and the fatigue threshold of that material. The required tensile stresses may be in the form of directly applied stresses or in the form of residual ... WebSCC failures have occurred in dry methanol, methanol/acid and methanol/halide mixtures.
