    Abstract: Catalysts used for the reaction between olefines, carbon monoxide and water to produce alcohols comprise an iron carbonyl, preferably iron pentacarbonyl, an amine, preferably a tertiary amine such as N-n-butylpyrrolidine, water and an optionally substituted ether, thioether, nitrile, lactam, carboxylic acid amide, a compound containing a sulphoxide group or two or more of such compounds. The additives are preferably present in an amount of 1-20% by weight based on the total weight of the three components forming the catalyst.ALSO:Alcohols having 3-7 carbon atoms are obtained from olefines having 2-6 carbon atoms, carbon monoxide and water at a temperature of 60-130 DEG C. in the presence of a complex catalyst consisting of iron carbonyl, an amine and water and an optionally substituted ether, thioether, nitrile, lactam, carboxylic acid amide, a compound containing a sulphoxide group or two or more of such compounds. The amine is preferably a tertiary one, e.g. N-n-butyl pyrrolidine. Among suitable additives specified are those of formula R1XR2, in which X is oxygen or sulphur and R1 and R2 are aliphatic, cycloaliphatic, araliphatic or aromatic radicals containing 1-12 carbon atoms substituted, for example, by esterified carboxylic groups, etherified hydroxy groups, esterified hydroxy groups, carboxylic groups, hydroxy groups and nitrile groups, and compounds of formula R3COYR4, in which Y is oxygen or a group NR5 in which R5 is hydrogen, an aliphatic, cycloaliphatic, araliphatic or aromatic radical both hetero atoms being members of a heterocyclic ring having 5-13 atoms as ring members and R3 and R4 together represent a polymethylene radical with 3-11 carbon atoms which together with -CO-Y- form a heterocyclic ring having 5-13 ring members. Suitable compounds of formula R3COYR4 are, for example, pyrrolidone, caprolactam, caprylic lactam, lauric lactam, N-methylpyrrolidone, and N-butylcaprolactam. Other suitable additives are N-mono- and N-disubstituted carbonamides, e.g. dimethyl and diethyl formamide, N.N-dimethyl acetamide, N.N-diethylbutyramide and benzoic and dimethyl amide. The additives are usually present in an amount of 1-20% by weight based on the total of the three components forming the catalyst and may be added during or after the formation of the catalyst. In the examples propylene is reacted with carbon monoxide and water in the presence of a catalyst comprising iron pentacarbonyl, N-butyl pyrrolidine and various additives as specified above to give a mixture of butanols. Specification 704,136 is referred to.

    Abstract: 1,137,686. Alkali metal salts of polyamine polyacetic acids. BADISCHE ANILIN- & SODA-FABRIK A.G. 29 April, 1966 [30 April, 1965], No. 18824/66. Heading C2C. Alkali metal salts of polyamine polyacetic acids are continuously produced from a non- aromatic polyamine, formaldehyde and an alkali metal cyanide (or hydrocyanic acid and alkali metal hydroxide) in aqueous solution at elevated temperature by effecting the reaction in a multistage cascade of reactors with a continuous supply of the reactants wherein the polyamine and alkali metal cyanide are used in a stoichiometric excess over formaldehyde (main reaction) in at least one stage, adding the remainder of the reactants in a subsequent stage, and in at least one further stage an after-reaction takes place in which the alkali metal cyanide content of the reaction product is decreased to a concentration less than 0À1% by wt., and at the same time ammonia is removed continuously from all the stages. The reaction is suitably effected at 60-120‹ C. at a pressure, for example of 0À5 to 3 atmospheres and ammonia formed may be removed by generating steam during the reaction or by passing an inert gas through the reaction mixture. The reaction mixture preferably flows in succession through from 3 to 8 separate reaction zones and the formaldehyde is suitably employed as a 20 to 40 wt. per cent aqueous solution. The concentration of the alkali metal cyanide in the final stage may be determined by metering in to the solution a small amount of formaldehyde. In the examples, the tetra-sodium salt of ethylenediamine tetraacetic acid is prepared, some nitrilotriacetic acid also being obtained.

    Abstract: Azo dyes are obtained by continuous diazotization of amines (see Division C2) and further reacting by coupling the diazo compounds obtained. Examples are given in which sulphanilic acid, metanilic acid, and p-chloroaniline are diazotized and coupled with b -naphthol or 1-phenyl-3-methyl-pyrazolone-(5).ALSO:In a process for the continuous diazotization of amines and for the recovery or further reaction of the diazo compounds formed, the reactants are continuously mixed and reacted and the heat of reaction is substantially absorbed by the reaction mixture with a rise in temperature, the diazo compound formed being recovered or subjected to further reaction either with retention or elimination of the nitrogen atoms, e.g. to form azo dyes, hydrazines, phenols or diazonium salts. Specified amines are primary monoamines and polyamines of aromatic character derived for example from benzene, condensed ring systems with 2 to 4 benzene nuclei to which heterocyclic rings may be anellated, heterocyclic compounds and derivatives thereof which contain side chains and/or inert substituents such as carboxylic, sulphonic, hydroxyl, amino and nitro groups, and halogen atoms. Diazotizing agents specified are solutions of nitriles in acids, nitrous acid esters or nitrosyl compounds. Two types of apparatus are described for carrying out the process. Examples are given for the diazotization of sulphanilic acid, metanillic acid, p-chloroaniline and aniline, and for the reduction of the diazo compounds to give hydrazines.

    Abstract: Aminoalkanol sulphuric acids, i.e. sulphuric acid monoesters of aminoalkanols are prepared by allowing an aminoalkanol and sulphuric acid to flow into a vigorously stirred suspension agent which agent is immiscible with water and is kept boiling at 70 DEG to 150 DEG C., the water formed in the reaction and any water supplied with the reactants being distilled off together with part of the suspension agent, the reaction being effected at atmospheric or subatmospheric pressure.
