Title: Process for the preparation of lactams
IPC: C07D211/76
Filed: 1963-05-27
Abstract: Lactams are made by hydroformylating an unsaturated aliphatic carboxylic acid, or an ester thereof, at above 180 DEG C. and treating the product with ammonia, or a primary amine, at above 260 DEG C. Specified starting materials for the hydroformylation stage, are acrylic, methacrylic, crotonic, cycloheptene isobutyric and dimethyl vinyl acetic acids and maleic and fumaric acids, and their esters, and sorbic acid esters.  Alkyl esters having alkyl groups of 1-3 carbon atoms are preferred.  Pyrrolidones are made from acrylic, or methacrylic, acids or their esters. Mixtures of pyrrolidones and piperidones are made from unbranched acids having a chain of more than 3 carbon atoms, or their esters, or from branched acids of more than 4 carbon atoms, or their esters. Acids of more than 4 carbon atoms, or their esters branched in the b  position; yield mainly piperidones.  Acids branched in the g  position yield pyrrolidones only. Preferably a polymerization inhibitor e.g. hydroquinone, is present. Preferably the molar ratio of CO:H2 is 1:1. The synthesis gas and the acids, or esters, are used in at least stoichiometric amounts. Preferably an excess of synthesis gas is used at 150-300 atmos. Conventional hydroformylation catalysts may be used, preferred being cobalt compounds e.g. complexes of cobalt carbonyls and trialkyl phosphines.  With the latter catalyst reaction may occur at 30-50 atoms.  1-5% of catalyst, by weight of the reaction mixture, is used generally as a solution, or suspension, in a liquid medium such as the acid or an ester thereof. Preferably the last stage of the hydroformylation reaction is effected at above 200 DEG C. Preferred hydroformylation temperatures are 220-280 DEG C.  Reaction times are generally 1-4 hours. Inert solvents e.g. benzene and cyclohexane, may be present.  The hydroformylation product need not be isolated before reaction with the nitrogen compound. Reaction with ammonia, or the amine, is preferably effected at 300-320 DEG C. The nitrogen compound is preferably used in excess e.g. a 20-500% molar excess, based on the acid or ester. If the hydroformylation product is acid it is preferably neutralised with a base e.g. caustic soda or lime, before reacting with the nitrogen containing compound. Solvents e.g. benzene, acetone and ethanol may be present. Specified amines are methyl, ethyl, lauryl, ethanol, cyclohexyl and dodecyl amines and aniline. Preferably the product is distilled in the presence of phosphorus pentoxide. The residual sludge contains catalyst residues which may be reactivated and used again. Examples are provided of the preparation of pyrrolidones and piperidones including the novel compounds N-methyl-, ethyl- and hexyl-b -methylpiperidone.

IPC: C01G21/14
Filed: 1951-09-10
Abstract: A double carbonate of lead and sodium, 5PbCO3.Na2CO3, is prepared as an intermediate in the manufacture of red lead by treating lead residues, or the like, after leaching to remove soluble salts, with a concentrated alkali metal hyposulphite solution free from sulphite, to dissolve the lead, followed by sodium carbonate solution to precipitate the double carbonate.  The alkali metal hyposulphite solution may be employed at a concentration of 580-700 gm./l at a temperature below 30 DEG C.  An almost saturated solution of sodium carbonate (250-300 gm./l.) may be employed and the solution of sodium carbonate and the alkali metal hyposulphite solution of lead may be poured simultaneously into a mixer such that there is a continual slight excess of Na2CO3 (7-11 gm./l.). After the double carbonate has been filtered off, the filtrate, after neutralization, may be used for extracting further quantities of lead.  According to a modification precious metals may be recovered from the neutralized filtrate by precipitation as sulphides, the filtrate then being suitably worked up and returned to the process.
