        Fischer synthesis produces variable quantities, depending upon the pressures used, of high-molecular-weight paraffins.  Oxidation of these by air transforms them into fatty acids, which can be esterified by means of synthetic glycerin made from propylene.  The product has received the name “synthetic butter.”  It is not certain that the synthetic product has the same physiological properties as natural fats.  Certain constituents are lacking, and they contain acids with both odd and even numbers of C atoms, whereas natural fats contain only the even-numbered atoms.
