Title: Improvements relating to the production of organic salts of bismuth
IPC: C07F9/94
Filed: 1931-10-29
Abstract: a -Carbethoxy-, a -carbopropoxy-, and a -carbobutoxy-cyclohexanyl acetic acids are prepared by partial hydrolysis respectively of diethyl-, dipropyl-, and dibutyl - cyclohexanylmalonic esters. Dipropyl - and dibutyl - cyclohexanylmalonic esters are obtained by hydrolyzing diethylcyclohexanylmalonic ester and esterifying the cyclohexanylmalonic acid with propyl or butyl alcohol in presence of sulphuric acid.  1 - Acetoxyhexahydrobenzoic acid is obtained by the action of acetic anhydride and anhydrous sodium acetate on 1-hydroxyhexahydrobenzoic acid.  By heating the latter with propionic acid and concentrated sulphuric acid the 1-propoxy-acid is obtained.ALSO:Oil-soluble bismuth salts are obtained by reacting on a carbalkyloxycyclohexanylacetic acid or a 1-acyloxyhexahydrobenzoic acid with a bismuth compound such as the oxide in the presence of water.  Elevated temperatures may be used for the reaction and the product be purified by solution in benzene.  The normal and basic salts of the first-named group of acids, and the basic salts of the second group are included in the invention.  The preparation of the normal and basic bismuth salts of a -carbethoxycyclohexanylacetic acid, and of the basic bismuth salts of a -carbopropoxy- and a -carbobutoxy-cyclohexanylacetic acids and of 1-acetoxyhexahydrobenzoic acid, is described in detail.  The bismuth salt of 1-propoxyhexahydrobenzoic acid is also specifically referred to.  a -carbethoxycyclohexanylacetic acid is prepared by partial hydrolysis of diethylcyclohexanylmalonate.  Dipropyl- and dibutyl-cyclohexanylmalonic esters are obtained by hydrolysing diethylcyclohexanylmalonic ester and esterifying the cylcohexanylmalonic acid with propyl or butyl alcohol.  Partial hydrolysis of the esters gives a -carbopropoxy- and a -carbobutoxy-cyclohexanylacetic acids.  1-acetoxyhexahydrobenzoic acid is obtained by the action of acetic anhydride and anhydrous sodium acetate on 1-hydroxyhexahydrobenzoic acid.  By heating the latter with propionic acid and concentrated sulphuric acid the 1-propoxy-acid is obtained.

Filed: 1920-10-29
Abstract: 179,204. Lamarque, R. Oct. 29, 1920. Stone, artificial.-In the manufacture of artificial stone from natural stone fragments the latter are crushed and graded by sifting, and the graded material is further crushed and sifted alternately until a dust-free product of uniform fineness corresponding to the natural grain of the stone is obtained. If the stone is crushed wet the grading is effected by repeated washings. The crushed stone is agglomerated bv means of a binding-agent capable, of hardening in the air or by baking. Pure or mixed cement, coloured or otherwise, burnt or wet clay, or kaolin may be used as binders. The composition may be applied to a core of reinforced concrete. After treatment with acids to remove calcium salts from the surface, the stone may be polished in the known manner.

Title: Process for the sulfonation of alkylaromatic compounds
Inventor: CHENICEK JOSEPH ALBERT
IPC: C07C303/06
Filed: 1958-09-26
Abstract: Alkylaromatic hydrocarbons and alkylphenols are sulphonated by reacting the given alkylaromatic compound, at a temperature in the range of from 0 DEG  to 70 DEG  C., with a sulphonating-agent comprising an addition-product formed from 0,5 to 3 moles of sulphur trioxide and 1 mole of aromatic hydrocarbon sulphonic acids or alkane sulphonic acids, the proportion of sulphonating-agent per one part by weight of alkylaromatic compound - to - be - sulphonated being within the range of 0,5 to 2 parts.  The process effects the mono-sulphonation of monocyclic aromatic hydrocarbons and phenols having an alkyl group of at least 9 carbon atoms, and of bicyclic aromatic hydrocarbons and phenols having an alkyl group of at least 5 carbon atoms.  In a preferred embodiment, the sulphonation-agent is prepared by mixing sulphur trioxide or oleum with some of the product of the process.  The invention is particularly advantageous in the production of alkyl aromatic sulphonic acids which are required to make detergents, because the products are free from coloured impurities.  For this purpose, suitable starting materials are : nonylbenzene, dinonylbenzene, decylbenzene, dodecylbenzene, didodecylbenzene, dodecyltoluene, pentadecylbenzene, amylnaphthol, amylnaphthalene, nonylnaphthalene, nonylphenol, and decylphenol.  In cases where the sulphonated product is not used as the complexing-agent, the latter is selected from sulphonic acids of low molecular weight, and at the end of the reaction the complexing-agent is separated from the product by means of a diluent such as butane, cyclohexane, chloroform, or trichloroethylene.  In an example, a sulphonating-agent is prepared by combining 0,75 mole of ethane sulphonic acid and 1,5 moles of sulphur trioxide, by bubbling a gaseous mixture of SO3 and n-butane into ethane sulphonic acid at 30 DEG  C.  This mixture is then stirred into one mole of dodecylbenzene maintained at about 25 DEG  C. over a period of about 20 minutes. The mixture is then stirred for 2 hours at 25 DEG -30 DEG  C. when substantially complete mono-sulphonation of the dodecylbenzene occurs.  Two volumes of chloroform are then added, and the mixture is allowed to stratify when a phase comprising approximately 85% of the ethane sulphonic acid, originally charged, separates from the chloroform-dodecylbenzene sulphonic acid phase, and is separated therefrom by decantation.  The chloroform solution is stirred with aqueous caustic solution, and the chloroform layer is then removed by decantation.  Evaporation of the aqueous extract yields light, cream-coloured sodium dodecylbenzene sulphonate which dissolves completely in water.

Title: Improvements in and relating to the production of cloudy phenol formaldehyde condensation products
IPC: C08K5/42
Filed: 1929-10-12
Abstract: Phenol-formaldehyde condensation products are rendered cloudy by the addition of esters of aromatic hydroxy compounds and inorganic non-volatile acids.  Phenol, naphthol and anisic alcohol are specified as suitable organic compounds and sulphuric or phosphoric as suitable acids.  Also suitable as acids are organic compounds, preferably aromatic, which have as a substituent group an acid radical such as naphthalene or benzene sulphonic acids. In an example naphthalene is sulphonated and then alkylated with isopropyl alcohol or alternatively sulphonated and alkylated in one stage using chlorsulphonic acid or oleum.  The isopropyl-b -naphthalene sulphonic acid is then esterified with b -naphthol in the presence of phosphorus oxychloride or phosgene to give the b -naphthol ester of isopropyl-b -naphthalene sulphonic acid.  In the second example phenol and formaldehyde are condensed in the presence of potassium hydroxide, over-acidified with acids having a low dissociation constant, such as lactic or formic acid, and dehydrated with or without the addition of solvents.  At the end of the dehydration, or just before, the benzene sulphonic ester of b -naphthol is added giving a mass which gives a white and opaque resin.
