摘要: Under an electron microscope, it was observed that the alkali metal soaps of 12-D(or L)-hydroxystearic acid separated out twisted fibers from various solutions. A symmetrical relationship regarding sense twist found between soap D-enantiomer and those L-enantiomer. In case D-enantiomer, right-handed for Li left-handed Rb Cs soaps. The Na- K- produced both fibers. solvent effect with respect to free its soap. cause twisting discussed in connection structure growth process crystal.
