Title: Improvements in or relating to the production of ketones
IPC: C07C45/00
Filed: 1952-10-20
Abstract: A higher ketone is produced by a method comprising passing a mixture containing an aliphatic or cycloaliphatic secondary alcohol containing from 3 to 7 carbon atoms and an aliphatic ketone containing from 3 to 7 carbon atoms in the vapour-phase over an alumina-copper catalyst at a temperature between 240 DEG  and 300 DEG C. and at a pressure above 175 lb. per square inch.  Suitable alcohols for starting materials are, for example, isopropyl alcohol, sec. - butyl alcohol, 2 - hydroxypentane, 3 - hydroxypentane, 2-hydroxyhexane, cyclohexanol, 4 - methylcyclohexanol and 2 - hydroxy heptane.  Suitable ketones are acetone, methylethyl ketone, methyl n-propyl ketone, diethyl ketone, hexanone-2, hexanone-3, methyl tert.-butyl ketone, di-n-propyl ketone and diiso-propyl ketone. Preferably the alcohol is one which on reduction yields a ketone identical with the ketone reactant, e.g. when methyl ethyl ketone is reacted with sec.-butyl alcohol.  The catalyst used preferably contains a major proportion of alumina, which has been rendered catalytically active, together with about 2-20 per cent of copper and optionally about 5 to 30 per cent of a difficultly reducible metal oxide having dehydrogenating characteristics, e.g. zinc oxide, manganese oxide, iron oxide, calcium oxide or magnesium oxide.  In the examples methyl ethyl ketone is reacted with sec.-butyl alcohol to give 5-methyl-3-heptanone and about 3,5-dimethyl-3-hexanone.ALSO:A catalyst used in the production of a higher ketone from an aliphatic or cycloaliphatic secondary alcohol and a ketone consists of an alumina-copper catalyst preferably including a major proportion of alumina which has been rendered catalytically active together with from about 2 to 20 per cent copper and optionally with from about 5 to 30 per cent. of a difficultly reducible metal oxide having dehydrogenating characteristics such as zinc oxide, manganese oxide, iron oxide, calcium oxide or magnesium oxide.  Preferably the alumina is first impregnated with a solution of a zinc salt, e.g. zinc nitrate, followed by roasting to convert the zinc salt to zinc oxide; the roasted catalyst is then impregnated with a solution of a copper salt, e.g. copper nitrate, and then roasted again to convert the copper salt to copper oxide; the copper oxide is then reduced to copper in a hydrogen atmosphere at elevated temperature.  In the examples the catalyst is prepared by (a) impregnating activated alumina with a concentrated aqueous solution of copper nitrate, followed by drying and roasting and then reducing it to a pure hydrogen at 250 DEG C.; (b) impregnating activated alumina with aqueous zinc nitrate, evaporating excess water and roasting; impregnating with aqueous copper nitrate solution, drying and roasting again and then reducing in an atmosphere of hydrogen at 280 DEG C.

Filed: 1975-06-23
Abstract: 1509769 Data storage HONEYWELL INFORMATION SYSTEMS Inc 23 June 1975 [24 June 1974 (2)] 26521/75 Heading G4C Data formed of variable length data fields VALUE (A), VALUE (B), ... Fig. 3(B), is recorded on storage means, such as a magnetic tape, with a separator, #AB, #BC, ... between adjacent fields, each separator being the logical combination of the lengths of the respective two fields or the logical combination of codes which indicate the types of the respective two fields and which index a table containing the lengths of the fields. The logical combination may be the exclusive-OR combination, the difference or the ring sum. At each end of the data is a separator A which is the logical combination of zero and the length or code of the adjacent field VALUE (A). Certain of the separators, e.g. #AB may be formed of two parts #AO, #OB to allow insertion of padding at block boundaries. Data recorded in this way may be scanned in either direction; this may be used, for example, in text editing. The recorded data may be arranged as a plurality of fibres each including a plurality of records each including a plurality of groups each including a plurality of fields, each adjacent pair of files, records, groups and fields being separated by a separator (Fig. 7, not shown). A desired field may then be accessed by skipping over files, records and groups not containing the desired field. A search may also be made to locate a record containing a data field having a desired content by extracting the content of a specified field of each record and comparing the extracted content with the desired content. When a desired field is located the locations and lengths of the relevant file, record, group and field are retained so that subsequent files, records, groups or fields may be accessed. Data is tested for errors in the separators by generating, using the separators, the location of each separator and comparing each generated location with the known location of the end of the data. An error is detected if a generated location is beyond the known end or if the locations of all the separators have been generated and the known end has not been reached. If an error is detected the data is scanned from the other end and again the location of each separator is generated; the separator for which the same location is generated in both scans is the separator containing the error.

Title: A process of producing carboxylic saturated and/or unsaturated acids, their salts and/or their ketol-esters
IPC: C07C51/00
Filed: 1935-09-27
Abstract: Saturated and/or unsaturated carboxylic acids, their metal salts, and/or their ketol esters are made by reacting a halogenated ketone having not more than 6 carbon atoms and one halogen atom or several halogen atoms, not more than two being attached to any one carbon atom, with water and a basic-acting alkali metal compound such as sodium hydroxide, carbonate, bicarbonate, or disodium phosphate, or an alkaline earth hydroxide.  Suitable halogenated ketones are chlorine, bromine and iodine derivatives of acetone, methyl ethyl ketone, diethyl ketone, methyl propyl and methyl isopropyl ketones, methyl butyl ketones, ethyl propyl ketones and their substitution products. Unsaturated products are formed from polyhalogenated ketones, at least one halogen atom preferably being attached to the carbon atom adjacent to the carbonyl group.  Particulars are given of the yields of different products obtained at different temperatures when chlorinated methyl ethyl ketone is hydrolyzed with different basic agents.  In examples: (1) chlormethyl ethyl ketone is hydrolyzed with sodium carbonate at 95--100 DEG  C.; from the product ethyl ketol and ketol ester are extracted with ether, then the remaining product is acidified and isobutyric acid is extracted with ether; methyl-ethyl acetic acid may be prepared similarly from chlormethyl propyl or isopropyl ketone; (2) chlormethyl ethyl ketone is hydrolyzed with sodium bicarbonate and after extracting with ether the neutral residue contains the ethyl ketol ester of isobutyric acid; the dimethyl ketol ester may be prepared similarly from a -chlor-ethyl methyl ketone and the propyl ketol esters of methyl acetic acid from chlormethyl propyl ketone; (3) a a <1>-dichlor methyl ethyl ketone is hydrolyzed with sodium carbonate, yielding crotonic and isocrotonic acids; angelic acid may be prepared similarly from a a <1>-dichlormethyl isopropyl ketone.  The ketonic esters are high-boiling liquids of good solvent properties and may be used as plasticizers in lacquers and the like.  They may be hydrolyzed to yield the ketols and acids. Specification 424,659 is referred to.  The Specification as open to inspection under Sect. 91 includes the use of any basic-acting metal compound such as calcium, magnesium or barium carbonate and is not limited to ketones in which not more than two halogen atoms are attached to the same carbon atom. This subject-matter does not appear in the Specification as accepted.
