This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1912 edition. Excerpt: ...after short b. (5 min.) give the hydroxylamine salt, m. 1o78, not 7'-phenylhydroxyaminobutyric acid, as previously reported; even after 240 hrs. b., there was no addition of NH, OH. Styrole, stilbene, w-bromo-and w-chlorostyroles, allyl alc. and amylene do not add NH, OH. w-Nitrostyrole after 1 hr. gives a-nitro-,3-phenyl-79-hydroxytaminoethane, m. 99--1oo. It is also formed after several days in the cold. Cinnamic anhydride after '/, hr. gives the hydroxamoxime hydrate; on longer b., the amino acid. Cinnamamide and cinnamhydroxamic acid likewise gave the hydroxamoximc hydrate alter '/, hr.; the latter gave 2 other unstable products to be described later. Cinnamonitrile in the cold or after 5 hrs. b. gives PhCH: CHC(: NOH)NH, . Cinnamaldehyde after 20 hrs. gives only the aldoxirne; after 200 hrs., a substance richer in N, m. 2o5--6. The formation of an aryl Me ketoxime having been noticed in some cases towards the end of the investigation, the reaction between PhCI-I: CHCO, H and NH, OH was again Studied to see whether this phenomenon was general, and such seems to be the case. The acid (37 g.) is b. 10 hrs. with 0.5 l. N N1-,0-I soln. in EtOH. On cooling, 7.7 g. of the amino acid seps. The mother liquors are evapd. almost to dryness, the raidue taken up in 150 cc. Na, CO, (about 0.66 N); 9.6 g. PhMeC.' NOH seps. in milky form and soon solidifies to a cryst. mass. Cans. A. Rournuza. Inversion of Saccharose (STOWARD). IIA.
