Title: Coffee aroma product and process for obtaining same
Inventor: FELDMAN JACOB RICHARD
IPC: A23L27/20
Filed: 1959-10-19
Abstract: Expressed coffee oil is distilled at a temperature below 100 DEG C. and an absolute pressure of less than 50 mm. of mercury. Low, medium and high boiling point components are removed successively, temperatures used ranging from 15 DEG  to 100 DEG C., from 20 DEG  to 35 DEG  C. being preferred.  The pressure is preferably between 4 microns and 10 mm. of mercury.  Preferably, the oil is distilled in a film of 10-100 microns produced by centrifuging. The material may all be condensed at -196 DEG C. or less but it is more economical to condense the aroma in stages, e.g. a first stage cooled with brine to between 0 DEG C. and -15 DEG C., a second stage cooled with solid carbon dioxide to -80 DEG  C. and a third stage cooled by liquid nitrogen to -196 DEG  C., or the first stage may be omitted to provide a two-stage process.  Inert gas, e.g. nitrogen, helium, carbon dioxide, may be passed over the expressed coffee oil to collect the more fugitive aromatic constituents, after which the higher boiling fractions are removed.  The aroma obtained may be used to aromatize soluble coffee powders, e.g. by passing inert gas over the aroma and then through the powder. Preferably, the aroma is incorporated in a lipophilic or oleaginous substance, e.g. oil or fat, which has a high boiling point.  Refined deodorized soybean oil, cottonseed coil, corn oil, coconut oil, peanut oil, lard, beef tallow, mutton tallow, or mineral oil may be used.  Clarified expressed coffee oil or de-aromatized, solvent extracted or hydrogenated coffee oil can be used.  In modifications, a falling film still may be used or the expressed coffee oil can be atomized into fine droplets in a chamber at reduced pressure.  A beverage made from roasted wheat, rye, chicory or the like, or the roasted product itself, may be aromatized.  The extract may also be used as a flavouring in ice-cream, icings, confections, syrups and the like, and an antioxidant may be added.  Specification 687,175 is referred to.

Title: N-substituted derivatives of diimidotriphosphoric acids and their production
IPC: C07F9/24
Filed: 1958-11-06
Abstract: The invention comprises N-substituted esters of diimido-triphosphoric acid of the formula <FORM:0839833/IV (b)/1> in which R0, R1, R2 and R3 are each selected from alkyl and aryl groups.  They may be obtained by reacting one mol. of a diamide of the formula R3OP(O)(HNR0)2 with two mols. of a chlorophosphoric acid ester of the formula ClP(O)(OR1)(OR2) in the presence of a stoichiometric amount of an alkali metal or alkali metal hydride in an inert diluent, e.g. benzene or xylene.  If an alkali metal is used it is preferred first to react this with the diamide to form the corresponding dialkali metal compound and then add the chlorophosphoric acid ester. Examples are given for the production of a compound in which R0, R1, R2 and R3 are each phenyl and of a compound in which each of the radicals R0, R1 and R2 is butyl and R3 is phenyl.

Abstract: 1,112,200. Heat-exchanging reactor. JAPAN GAS-CHEMICAL CO., Inc. 24 Aug., 1965, No. 36350/65. Heading B1X. A catalytic reactor for exothermic gas phase reactions has a fixed catalyst bed cooled by heat exchange with feed gas which is passed through the bed in double concentric tubes, the inner of which receives the gas at one end, is closed at the other and delivers the gas through apertures spaced at intervals along its wall to the outer tube which is closed at the entry end of the inner tube and open at the closed end of the inner tube. The feed gas thereby cools the bed before passing to the entry zone of the catalyst bed. In Fig. 5, feed gas enters the apparatus from valve 8 by pipe 9 to the space 12 between the reactor pressure shell 1 and the bed container 2, and passes thence through heat exchanger 3 to the cooling tubes 22 along with gas from pipe 10 and exchanger by-pass 28. The heated gases pass from zone 17 through central pipe 18 to bed entry zone 19. Reacted gases leave by exchanger 3 and pipe 27. In another embodiment (Fig. 1, not shown), straight cooling tubes are used, which are alternately cocurrent with and countercurrent to the flow of the gases in the bed, gas being supplied to the tubes from both ends of the reactor. The apparatus is of particular application in the high temperature and high pressure synthesis of ammonia and methanol.
