Title: New antibiotic amycine and a process for its preparation
Inventor: CRAVERI RENATO
Filed: 1958-10-23
Abstract: <PICT:0922952/IV(a)/1> <PICT:0922952/IV(a)/2> An antibiotic amycine, active against gram positive and negative bacteria and fungi, is produced by cultivating Streptomyces lavendulae strain 1307, or a mutant thereof, in an aqueous nutrient medium containing a source of carbon, nitrogen and mineral salts under aerobic conditions preferably submerged.  The pH is adjusted to pH 6,0 and cultivation is at 20-35 DEG C. for 2 to 6 days.  A typical medium contains corn steep liquor, maltose, sodium chloride and water.  Amycine is recovered from the clarified broth by adsorption on activated carbon under alkaline conditions especially at pH 9,8 and elution with an acid eluant, e.g. acidified methanol.  The crude salt is precipitated from the concentrated eluant by the addition of acetone. Purification is obtained by dissolving in water and adding aqueous methyl orange to form amycine helianthate, which is reconverted to the hydrochloride by treatment with HCl in methanol.  Excess acid is removed by treatment with a basic ion exchange resin.  Further purification is obtained by (a) dissolving in a solvent and adding a non-solvent (b) adsorption on acid washed aluminium oxide to remove impurities.  Amycine is a basic antibiotic containing only carbon, hydrogen and nitrogen; the hydrochloride is a white hydroscopic powder soluble in water and methanol but insoluble in acetone, butanol, pyridine, chloroform, ethyl acetate, petroleum ether and benzene, the elementary analysis being C=41,48, H= 7,58, Cl=8,42 and N=13,58; the sulphate has an elementary analysis of C=32,16, H= 6,33, S=6,71 and N=15,63; the helianthate has a melting point at 209 DEG C. and analysis C=48,07, H=7,08, S=4,95 and N=15,54; the Reineckate has a melting point of 173-176 DEG C. and a nitrogen content of 21,45 per cent.; the sulphate showing characteristic absorption in the infra red at 2,9, 3,03, 5,85, 6,0, 6,0, 6,45, 7,64, 8,8, 9,03, 10,27, 10,50, 10,72, 11,78 m .

Abstract: 342,764. Spray carburetters. DOUGLAS MOTORS, Ltd., Hanham Road, and DOUGLAS, J., Woodstock, both in Kingswood, Bristol. Nov. 7, 1929, No. 33933. [Class 7 (iii).] In governor-controlled carburetters, particularly for stationary engines of electric lighting sets, the governor actuates means by which a light fuel is used at starting and a heavier fuel after the engine has warmed up. The main carburetter is supplied with paraffin from a float-chamber 1, and has a throttle valve held normally open by a spring 3 engaging a head 4 on the spindle 2. A bell-crank lever mounted on a bracket 5, has one arm 8 connected by a link 9 to the governor, the other arm 7 being adapted to engage in succession a plunger 14 and the head 4 of the throttle valve. The plunger, at its lower end, has a transverse passage 16 which, when the plunger is raised, permits a petrol-air mixture produced in carburetter 11-13 to pass. This occurs when the throttle is fully open and the engine is being started. As the engine speed increases, the arm 7 depresses plunger 14, cuts off the petrol mixture and admits air only past the lower end of the plunger. Ultimately the suction becomes sufficient to bring the paraffin into use. In a modification, the plunger has an axial bore which surrounds the petrol nozzle, mixture being withdrawn through a lateral port which is masked when the plunger is lowered.

Filed: 1945-12-21
Abstract: Dinitro compounds are produced by reacting an olefine in the presence of an inert liquid organic solvent with nitrogen tetroxide under pressure of at least 20 lb. per sq. inch absolute. Nitro alcohols may be produced by treating the liquid which remains after separating the dinitro compound with water. Suitable olefins are e.g. ethyl, and higher aliphatic mono-olefines such as propylene, butylene, amylene; di-olefines such as butadiene; cycloaliphatic olefines, e.g. cyclohexene and olefines containing an aromatic group, e.g. styrene. The solvent preferably dissolves both reactants and both solvent and reactants should be substantially free from water.  Suitable solvents include carbon tetrachloride, chloroform, glacial acetic acid, ligroin and ether.  Pressures of 20-1500 lb. per sq. inch absolute may be used and in the case of olefines containing up to 4 carbon atoms the temperature should be 0-60 DEG  C.  In examples: (1) a solution of nitrogen tetroxide in carbon tetrachloride is maintained under a nitrogen pressure of 100 lb. per sq. inch and ethylene is passed in, 1,2-dinitroethane is recovered and 2-nitroethanol is obtained from the oily residue after dilution with ether and washing with water; (2) as in (1) the same products are obtained, but no nitrogen is used, the pressure being maintained by addition of ethylene; (3) ethylene is passed into carbon tetrachloride at 100 lb. per sq. inch and a solution of nitrogen tetroxide in carbon tetrachloride is added simultaneously under a pressure of nitrogen of 100 lb. per sq. inch, crude 1,2-dinitroethane is recovered; (4) ethylene is passed into a solution of nitrogen tetroxide in glacial acetic acid to a pressure of 100 lb. per sq. inch.  Crude 1,2-dinitroethane is obtained; (5) a solution of butadiene in carbon tetrachloride is added to a solution of nitrogen tetroxide in the same solvent at 0 DEG  C. and at 50 lb. per sq. inch.  An oily nitrocompound is obtained.  Specifications 532,686, 572,949, 580,260 and 587,992 are referred to.
