Thomas Percy Hilditch

from Wikipedia, the free encyclopedia

Thomas Percy Hilditch , known as TP Hilditch, (born April 22, 1886 in London , † August 9, 1965 in Birkenhead ) was a British chemist. He is known for contributions to the chemistry of fats and was considered a leading authority in the UK.

Hilditch studied from 1904 Chemistry at University College London with a Bachelor's degree in 1907 with honors. One of his teachers was William Ramsay . He then studied until 1909 in Jena (with Ludwig Knorr ) and Geneva (with Philippe Auguste Guye ) and received his doctorate in 1911 at Samuel Smiles at the University of London (D. Sc.) Before the mediation of Ramsay for soap manufacturer Joseph Crossland in Warrington went where he began to work with fats and specifically catalytic hydrogenation of fats (published 1919-1925 in Proc. Royal Society A, in part with EF Armstrong). Before that, he had dealt with the most varied areas of chemistry and at the time of his dissertation had already published 30 articles and three books. During the First World War, he developed industrial syntheses for the war- essential acetone from ethanol and acetic acid for amyl acetate at the company . He stayed with the company until 1926 when, through the legacy of chemistry professor James Campbell Brown, a chair in industrial chemistry was created at the University of Liverpool , which Hilditch was the first to hold. In 1951 he retired.

Hilditch was a pioneer in systematic research into fats and industrial fat chemistry. He demonstrated the triglyceride structure of naturally occurring fats, systematically examined vegetable and animal fats (presented in his main work The chemical constitution of natural fats) and created analysis methods for fats at a time when gas and thin-layer chromatography was not yet in general use and the spectroscopic methods available to Hilditch were limited. He examined their auto-oxidation and rancidity -Will, drying oils and conclusions of the fat composition on the evolution of living beings.

He was a Fellow of the Royal Society (1942), CBE (1952). He received the Chevreul Medal of the French Groupement Technique des Corps Gras in 1964, the Lampitt Medal of the Society of Chemical Industry in 1962 and the Alton E. Bailey Award in 1965. He was first chairman and in 1951 co-founder of the Oils and Fats Section of the Society of Chemical Industry.
