Phosphoric acid as an eka-catalyst in the alkylation of pipe still vapors
… this research, it is evident that pipe still vapors composed of ethylene and propane cannot be alkylated at atmospheric pressure and relatively low temperatures with the use of 85-100 per cent ortho-phosphoric acid as a catalyst. No mechanism of reaction has been proven.

A statistical analysis of data on the corrosion of aluminum in hydrochloric acid vapors
In this thesis, corrosion data were subjected to statistical analysis for the purpose of obtaining meaningful estimates of the specific rate of reaction and the energy of activation and obtaining a response equation for prediction of weight gain. A two-stage analysis was used in the estimation of …
