Acid Cerotic

Langmuir also gave needed emphasis to the importance of employing pure substances rather than the various natural oils previously used. He thus found that the limiting area (at the Pockels point) was the same for palmitic, stearic, and cerotic acids, namely, 21 per molecule. (For convenience to the reader, the common names associated with the various hydrocarbon derivatives most frequently mentioned in this chapter are given in Table IV-1.)... [Pg.102]

The table shows that many molecules are far from being symmetrical in shape, a direct confirmation of his theory. We notice incidentally the need for care in calculating the number of molecular layers contained in a thin film by the method of Rayleigh and Devaux, without further consideration. (If for example Devaux had chosen cerotic acid instead of triolein as his test case, he would have found 31 A. as the thickness of the film, whereas the cube root of the volume of a molecule is 31x25 = 9 2 A. Thus, neglecting the shape of the molecule, cerotic acid would have appeared to form a trimolecular layer.)... [Pg.72]

Carnauba wax (Brazil wax) comes from leaves of the Copernicia cerifera, a South American palm tree. It melts at about 185° — 195°F, and is the hardest and toughest of the natural waxes. It consists mostly of all cerotic acid ester of myrical alcohol... [Pg.325]

Beeswax, White, occurs as a yellow-white solid, somewhat translucent in thin layers, with a faint, characteristic odor, free from rancidity. It is the bleached, purified wax from the honeycomb of the bee Apis mellifera L. (Fam. Apidae), and it consists primarily of myricyl palmitate (myricin), cerotic acid and ester, and some high-carbon paraffins. Its specific gravity is about 0.95. Beeswax, White, is insoluble in water and sparingly soluble in cold alcohol. Boiling alcohol dissolves cerotic acid and part of the myricin. It is completely soluble in chloroform, in ether, and in fixed and volatile oils. It is partly soluble in cold carbon disulfide and is completely soluble in it at temperatures of 30° or above.
