First order rate constants and Arrhenius parameters have been obtained for the thermal decomposition of 1‐hexadecyl hydrogen sulphate. From published data on thermal decomposition of lauryl hydrogen sulphate and lauryl ether hydrogen sulphate, first order rate constants and Arrhenius parameters have been obtained. The agreement between the two sets of data for the two alkyl hydrogen sulphates is within the 95% confidence limits, a combined Arrhenius plot giving an activation energy of 12.69 ± 1.97 K cal mol −1 and pre‐exponential factor of 10 (4.68 ± 1.24) sec −1 . For lauryl ether hydrogen sulphate, a 3‐point Arrhenius plot gives an activation energy of 9.4 K cal. mol −1 and a pre‐exponential factor of 10 2 sec −1 .
