Abstract: 514,722. Adsorption of gases. SUTCLIFFE. E. R. Feb. 12, 1938, Nos. 4480/38 and 4725/39. [Class 1(i)] An apparatus for recovering solvent or vapour from solvent or vapour-laden air comprises in addition to the main adsorption filter, an auxiliary filter into which the air remaining in the main filter at the end of a charging phase is passed and stripped of solvent, air being passed through the auxiliary filter in each charging phase of the main filter to remove part of the solvent which is returned to the main filter for recovery. The vapour or solventladen air from conduit el is fed through a dust extractor e, fan d, and pipe b to the main adsorption filter a. The stripped air passes through an outlet c to a pipe c<1>, and valves b<2>, b<3> are provided so that the vapour-laden air may in certain circumstances bypass the main filter a during the flushing process. The air in the filter a at the end of the charging process is driven by the steam through a pipe f<1> and valve f<4> to the auxiliary filter provided with a pipe f<3> connected to the suction side of 'the fan d preferably by opening into the casing of the dust-extractor e. The valve f<4> is opened during the charging phase and the air drawn through the inlet f<2> sweeps the vapour out of the auxiliary filter from which it passes to the main filter. Specification 474,230 is referred to.

Title: Manufacture of polymethine dyestuffs
IPC: C09B23/06
Filed: 1929-02-13
Abstract: 328,357. Kuhn, R., and Winterstein, A. Feb. 13, 1929. Samples furnished. Cyclammonium polymethine dyes are prepared by condensing with formic acid or a formate, a methylene base of a cyclic ammonium salt having an active methyl group in the a- or gamma-position. Instead of the methylene base, a salt thereof with an organic acid may be used. By this process polymethine dyestuffs substituted in the 7: 7<1>- positions can be obtained. Thus formic acid or formates can be condensed with the methylene bases of compounds having the general formula : in which X is a divalent residue such as -CH2-, - S-, or -CH=CH-; Y is an acid radicle; z is a substituent such as CH3, halogen or alkoxy and R is an alkyl group. According to examples : (1) the crude methylene base, corresponding to the methyl iodide of #-naphtho quinaldine obtained by extracting ether, after the addition of caustic soda lye to an acetone solution of the quinaldinium salt, is condensed in the presence of acetic anhydride with formic acid, whereby 1 : 1<1>- dimethylstreptomonovinylene - 2 : 2<1>-# : #<1>-naphthoquinocyanineacetate is produced. Instead of the methylene base of the methyliodide of #- naphthoquinaldine, the bases corresponding to the methyl iodides of a-naphthoquinaldine, quinaldine, 8-chlorquinaldine, 4-carboxyquinaldinemethylester, 8-methylquinaldine, 8-methoxyquinaldine, 8-ethoxy quinaldine, 2: 3:-31-trimethylindolenine, and 9-methylacridine may be used; (2) 1-methyl-2-methylenebenzthiazoline is condensed with formic acid in the presence of acetic anhydride to give 1: 1<1>-dimethylstreptomonovinylene-2: 2<1>-thiocyanine, and 1: 3: 3: 7-tetramethyl-2-methyleneindolene are condensed with formic acid to give 1 : 1<1> : 3: 3: 3<1> : 3<1> : 7: 7'- octa- and 1 : 1<1> : 3 : 3 : 3<1> : 3<1> : 4: 4<1> : 7 : 7<1>-decamethylstreptomonovinylene-2: 2<1>-indocyanine; (3) the chloride of 1: 1<1>: 3 : 3 : 3<1> : 3<1>-hexa-methyl streptomonovinylene-2 : 21-indocyanine is obtained bv reacting formic acid with a mixture of the methyliodide of 2: 3: 3 : trimethylindolenine and the corresponding base; (4) 1 : 2 : 3 : 3-tetramethyl indoleninium trichloracetate (obtained from the corresponding methylene base by treatment with chloracetic acid in alcoholic solution) is dissolved in acetic anhydride and treated with formic acid. 1 : 3 : 3 : 7-Tetra- and 1 : 3: 3 : 4: 7-pentamethyl-2-methylencindolins are prepared from o-toluidine and p-xylidine by forming the corresponding 2-methyl indol (by condensing the tolyl and xylyl hydrazines with acetone and closing the ring) and subsequently treating with methyl iodide; the 2-methylene bases are liberated by treating the resulting cylammonium iodides with alkali. 8-Ethoxyquinaldine is prepared by reacting ophenetidine with paraformaldehyde in the presence of hydrochloric acid. Specification 232,740 is referred to.
