TL;DR: In this paper, the kinetics of the Oxidation of several sodium p-alkylbenzenesulfonates by aqueous dichromate have been studied under slightly acidic conditions.
Abstract: The kinetics of the Oxidation of several sodium p-alkylbenzenesulfonates by aqueous dichromate have been studied under slightly acidic conditions (pH = 7.0 to 5.4). The results indicate that the on...

TL;DR: In this paper, it was shown that 4,4-dimethylcholest-5-ene-3-one with sodium dichromate has been shown to give the γ-lactones 3,3-dimethyldimethyl-2-oxa-A-nor-5 -ene-1,7-dione and 3, 3-dimmethyl-2.5 -oxa -a-nor -5 −ene -1.1-one, respectively.
Abstract: Oxidation of 4,4-dimethylcholest-5-ene-3-one and 4,4-dimethyl-5α-cholestan-3-one with sodium dichromate has been shown to give the γ-lactones 3,3-dimethyl-2-oxa-A-norcholest-5-ene-1,7-dione and 3,3-dimethyl-2-oxa-A-nor-5α-cholestan-1-one, respectively.

TL;DR: In this article, an oxide film is formed on the surface of an Al or Al alloy body to be treated by anodic oxidation, and the body is treated in a pore sealing soln such as an aqueous soln.
Abstract: PURPOSE:To improve the heat resistance of an oxide film formed on the surface of an Al or Al alloy body to be treated by treating the body to seal the pores in the oxide film and by heating it to a specified temp. CONSTITUTION:An oxide film is formed on the surface of an Al or Al alloy body to be treated by anodic oxidation. The body is treated in a pore sealing soln. such as an aqueous soln. of sodium dichromate or deionized boiling water to seal the pores in the oxide film, and it is immediately heated to 140-200 deg.C, especially 170-190 deg.C and held at the temp. for 30-60min, especially 40-50min.

TL;DR: Acute sodium dichromate poisoning is a rare occurrence but incidences of accidental or suicidal ingestion of compounds like this may increase due to its wide use and easy accessibility in textile, printing and paper works the demand for which has increased over the last few years.
Abstract: Acute sodium dichromate poisoning is a rare occurrence. But incidences of accidental or suicidal ingestion of compounds like this may increase due to its wide use and easy accessibility in textile, printing and paper works the demand for which has increased over the last few years. Diagnosis in such cases can only be done based on the history, clinical and postmortem findings. Chemical analysis in such cases may not be helpful.
