518 EXPERIMENT STATION RECORD. 



Chemical technology and analysis of oils, fats, and waxes, J. Lewkowitsch 

 (London, 1D09, J/, ed., rev. and enl., vols. 1, pp. XX+o.',2, figs. 5h' 2, pp. XI+S16, 

 figs. 20; 3, pp. VIII+J1O6, figs. 28). — This new edition has been revised and en- 

 larged to include recent investigations and statistical data on the commercial 

 importance of oils, fats, and waxes. More attention has been given to the 

 manufacturing processes and to the historical development of analytical 

 processes than in earlier editions. Emulsified oils, fatty acid industry, and 

 technology of waxes are titles of new sections which have been added. The 

 footnotes contain complete references to patent literature. 



Theory of the hydrolysis of fats and oils, J. Kellner (Chcm. Ztg., 33 

 {1909), No. 50, p. JfSS, fig. 1; al)s. in Jour. 80c. Chein. Indns., 28 {1909), No. 

 10, p. 531). — In 3 analyses of palm-nut oil the respective amounts of glycerol 

 found were 12.16, 5.2S, and 2.11 per cent, as against 10.22, 3.17, and 1.37 per 

 cent theoretically required for a quadrimolecular hydrolysis. The author con- 

 cludes that mono- and diglycerids are present in fats partially hydrolyzed in 

 an autoclave either by means of zinc oxid or of water alone, but not in those 

 hydrolyzed with an aqueous solution of alkali under atmospheric pressure. 



Investig'ation of linolenic acid in linseed oil, E. Erdmann and F. Bedford 

 {Ber. Dent. (Jhcm. GeselL, 42 {1909), No. 6, pp. 132^-1333; abs. in Jour. Soc. 

 Chem. Indus., 28 {1909), No. 10, pp. 530, 531).— A yield of 15.3 per cent of lino- 

 lenic hexabromid was obtained from the mixed fatty acids of the oil. The 

 authors term the acid which yields tbe hexabromid a-linolenic acid. Other 

 data are reported. 



Constitution of linolenic acid, E. Erdmann, F. Bedford, and F. Raspe {Ber, 

 Deut. Chcm. GeselL, 1,2 {1909), No. 6, pp. 133.',-13',6; ahs. in Jour. Soc. Chcm. 

 Indus., 28 {1909), No. 10, p. 5.3i).— "The linolenic acid obtained by the reduc- 

 tion of the hexabromid from the mixed fatty acids of linseed oil [see previous 

 abstract] when treated with ozone, yields a mixture of two ozouids, CisHaoOn 

 (or ozonid-peroxids, CisHsoOis), while the ethyl esters form' ozonids with the 

 composition, C-oHsiOn (or C20H34O12)." 



Oil of colocynth seeds, C. Grimaldi and L. Prussia {Bol. Chim. Farm., 

 J,8 {1909), pp. 93-95; abs. in Chem. Zentbl., 1909, I, No. 18, p. l.>,89; Jour. Soc. 

 Chem. Indus., 28 {1909), No. 10, p. 531). — " Colocynth seeds from Algiers, when 

 extracted with carbon tetrachlorid, yielded a yellowish-red oil showing a faint 

 green fluorescence and having a somewhat bitter taste and a slight odor char- 

 acteristic of oils from Cucurbitacejne. The oil was soluble in boiling absolute 

 alcohol, and in ether, petroleum ether, chloroform, benzin, carbon bisulphid, 

 and amyl alcohol, but only slightly soluble in boiling 95 per cent alcohol." 



Preparation and chief characters of samphire oil, F. Borde {Bui. Sci. 

 Pharmacol., 16 {1909), pp. 132-142; abs. in Chem. Zentbl., 1909, I, No. 19, pp. 

 1566, 1567; Jour. Soc. Chem. Indus., 28 {1909), No. 11, pp. 623, 63^).— Analytical 

 data are reported of oils obtained from the leaves, stalks, and fruit of the sam- 

 phire plant {Critlunuin muritimu)ii). 



Analysis of the oil from the seeds of Symphonia g^lobulifera, .J. E. South- 

 combe {Jour. Soc. Chem. Indus., 28 {1909), No. 10, pp. J,99, 500).— Analytical 

 constants are reported. 



Some Sudan fats and oils, W. Beam {Rpt. Wellcome Research Labs. Gordon 

 Mem. Col. Khartoum, 3 {1908), pp. 4i2-//i.)).— Analytical data are reported of 

 oils obtained from Balanites cegyptiaca, Butyrospermum parlcii, and Lophira 

 alata. 



The composition of shea butter, J. E. Southcombe {Jour. Soc. Chem. Indus., 

 28 {1909), No. 10, p. 499).— The author reports analytical data on shea butter, 

 which Is used with considerable success in soap making.
