Title: Improvements in or relating to the production of ketones
Filed: 1952-11-21
Abstract: Ketones are made by reacting aliphatic alcohols with aliphatic ketones in the vapour phase in the prescene of a dehydrating-dehydrogenating-catalyst at above about 175 p.s.i.g. and at an elevated temperature, and thereafter passing the resulting vaporous reaction mixture over a catalyst containing a dehydrogenating component at between about 15 and 50 p.s.i.g. and at an elevated temperature.  The ketone obtained has a number of carbon atoms per molecule equal to the sum of those present in the alcohol and ketone.  Many dehydrating dehydrogenating catalysts are indicated representative of dehydrating components being oxides and carbonates of aluminium, barium and thorium and of dehydrogenating components copper, silver, iron and zinc as such or as oxides or salts.  The second stage catalyst may also contain a dehydrogenating component and preferably the same catalyst is used in both stages.  First stage catalysts whose activities have been induced may be used in the second stage and may be superior to fresh active catalyst. Preferably temperatures of 240-390 DEG  C. are used in the first stage and one of above 225 DEG  C. in the second stage.  Preferably the alcohol and ketone reactants each contain 3-7 carbon atoms.  The ketonic reactant may be formed in situ from an alcohol or a feed comprising ketone and hydrogen only may be used in which case an alcohol is formed in situ.  Compositions of feeds and flow rates are not critical, a preferred flow rate being from about 1 to 4 in terms of liquid hourly space velocity. In examples (1) the catalyst is obtained by impregnating activated alumina with copper nitrate, drying, roasting and reducing in pure hydrogen and is placed in two reactor tubes a substantially equimolar mixture of methyl ethyl ketone and secondary butanol being passed at 255 DEG  C. and 250 p.s.i.g. through the first reactor and at approximately the same temperature and at about 30 p.s.i.g. through the second reactor to yield 5-methyl-3-heptanone with a small quantity of 3,4-dimethyl-2-hexanone, after about 400 hours conversion the unit is closed down, catalyst in the second stage regenerated with air and hydrogen treatments and the reaction restarted with the flow of gases reversed, another regeneration of catalyst and reversal of feed flow also being described; (2) is as (1) save that the second stage catalyst is made by impregnating calcined diatomaceous earth with nickel nitrate, drying, roasting and reducing and no reversal of gas flow is described; and (3) is as (1) save that the feed is an equimolar mixture of secondary butanol and isopropanol yielding C6, C7, C8 and higher ketones any C3 and C4 ketones being recycled after dehydration.  Reference has been directed by the Comptroller to Specification 723,280.

Abstract: Esters of phenylcarbamic acids of the general formula <FORM:0734745/IV (b)/1> in which R1 and R3 represent alkyl or alkoxy groups, R2 represents hydrogen or an alkyl or alkoxy group, R4 is a branched or unbranched saturated or unsaturated, hydrocarbon chain having at the most 6 carbon atoms, and R5 and R6 represent hydrogen or alkyl groups which together with the nitrogen may form a heterocyclic ring, are made by reacting a phenylcarbamic ester of the formula <FORM:0734745/IV (b)/2> where R7 is a straight, branched or cyclic saturated or unsaturated hydrocarbon chain, with an amino alcohol of the formula HO-R4-N.R5.R6 in the presence of an alkali or alkaline earth metal.  Preferably the reaction is carried out using an excess of the amino alcohol at an elevated temperature and under reduced pressure so that the alcohol R7.OH formed during the reaction is distilled off.  In examples: (1) the methyl ester of 2 : 6-dimethyl phenylcarbamic acid is heated with diethylaminoethyl alcohol to give the 2 : 6-dimethyl phenylcarbamic acid diethylaminoethyl ester; and (2) 2 : 4 : 6 - trimethyl phenylcarbamic acid ethyl ester is heated with piperidinoethyl alcohol to give 2 : 4 : 6-trimethyl phenylcarbamic acid piperidinoethyl ester.
