In continuation of the sulphation of fatty acids (Part 19) castor oil and its fatty acids and oleic acid and oleyl alcohol were sulphated at room teperature to study the effect of concentrated sulphuric acid on the same under identical conditions and also to compare the rates of sulphation of these. [...] The mechanism of the reaction of sulphuric acid with castor oil and its fatty acids is of importance from the point of view of the manufacture of Turkey red oils. [...] In this particular case it is (17.95-10.28) — From the various results tabulated it is possible to calculate the (i) extent of hydrolysis of the glycerides of castor-oil (ii) extent of hydrolysis of pre-formed sulphuric esters (iii) amounts of sulphuric acid reacted with the double bond and with the OH group. [...] From the figure one can find (i) the extent of hydrolysis of the glycerides by the difference of sulphuric acid reacted with castor oil and castor oil fatty acids calculated by fall in A. V. by the difference of curves I. and 2 ; (ii) the extent of hydrolysis of pre-formed sulphuric esters by the difference between curves 4 and 3 ; (iii) the quantity of sulphuric acid reacted with the OH group by [...] Authentic samples of the various varieties of cottonseeds were obtained by the courtesy of the Agriculture Department of Hyderabad State from 1950 and 1952 crops The two samples from the Hubli district were received through a private party and the market sample was purchased locally."88 V.
