MANDAUE, a town of the province of Cebu, island of Cebu, Philippine Islands, on the E. coast and E. coast road, about 4 M. N.E. of the town of Cebu, the capital. Pop. (1903), 11,078; in the same year the town of Consolacion (pop. 5511) was merged with Mandaue. Its climate is very hot, but healthy. The
It crystallizes from water in large rhombic crystals, which melt at 118° C. Oxidizing agents convert it into benzaldehyde. When heated with hydriodic acid and phosphorus it forms phenylacetic acid; whilst concentrated hydrobromic acid and hydrochloric acid at moderate temperatures convert it into phenylbrom- and phenylchlor-acetic acids. The inactive mixture may be resolved into its active components by fractional crystallization of the cinchonine salt, when the salt of the dextro modification separates first; or the ammonium salt may be fermented by Penicillium glaucum, when the laevo form is destroyed and the dextro form remains untouched; on the other hand, Saccharomyces ellipsoldeus destroys the dextro form, but does not touch the laevo form. A mixture of the two forms in equivalent quantities produces the inactive variety, which is also obtained when either form is heated for some hours to 16o° C.
