Title: Synthetic resin coating composition and process of producing the same
IPC: H01B3/36
Filed: 1957-10-08
Abstract: A wire enamel comprises a solution in an organic solvent of (a) 100 parts of a "neu-tralized" polyvinyl acetal resin (i.e. a polyvinyl acetal not acting as an acidic material); (b) 5-100 parts of a soluble phenol-aldehyde resin obtained by reacting 1 mol. of a phenol with 0.7-2.0 mol. of a lower aldehyde under alkaline conditions; and (c) a minor amount of an acidic substance consisting of sulphuric acid, phosphoric acid, benzene phosphonic acid, hypophosphorous acid, phosphorous acid or an ammonium salt or alkyl ester of one of said phosphorus acids.  The polyvinyl acetal may contain 1-30% ester groups and 3-25% alcohol groups and may be acetalized with formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde or mixtures thereof and in the examples it is made by reacting polyvinyl acetate dissolved in glacial acetic acid with the aldehyde in the presence of sulphuric or hydrochloric acid.  After acetalization, the acid catalyst is neutralized (e.g. with ammonia, KOH or triethanolamine) and water added to precipitate the resin followed, if desired, by steeping the precipitated resin in a base (e.g. an alkali hydroxide, a tertiary amine, hexamethylene tetramine, methacrylol urea or di-o-toluylguanidine).  In the manufacture of phenolaldehyde resin, the phenol may be phenol, cresols, xylenols, ethylphenol or p-t-butylphenol; the aldehyde may be formaldehyde, acetaldehyde or butyraldehyde; and the catalyst may be triethanolamine.  The resin solvent may be cresol, furfural, coal tar naphtha, toluol or xylol.

Title: Alkyl (1-p-menthen-6-yl) ketones
IPC: C11B9/00
Filed: 1959-09-18
Abstract: p-Menthenyl alkyl ketones of the general formula  <FORM:0870001/IV (b)/1> wherein R is a lower alkyl group, are produced by treating 1-p-menthene with an aliphatic acid anhydride in the presence of a catalyst, preferably zinc chloride.  In Example 2, 1-pmenthene is introduced into a solution of anhydrous zinc chloride in propionic anhydride, at a temperature of about 30 DEG C., and the mixture is agitated for 3 hours.  The mixture is then agitated with water, and allowed to separate.  The upper liquid layer is separated, neutralized with caustic soda, and submitted to fractional distillation under reduced pressure to isolate ethyl (1-p-menthen-6-yl) ketone.  The product is optically-active or racemic depending on the 1-p-menthene used as starting material. 1-p-menthyl propionate is obtained as byproduct.  The ketones may be used as soapperfumes (Group III).ALSO:p-Menthenyl alkyl ketones of the general formula <FORM:0870001/III/1> wherein R is a lower alkyl group, are suitable for use as soap-perfumes.  In an example, 1 part of ethyl (1-p-menthen-6-yl) ketone when mixed with 99 parts of white milled toilet soap, gives the soap a strong petitgrain-like odour. The corresponding butyl compound is also referred to as a soap-perfume.

Patent GB-948893-A (GB)
Title: Improvements in or relating to ª -furyl propionic acid esters
Filed: 1962-08-22
Abstract: The invention comprises compounds of the formula: <FORM:0948893/C2/1> wherein R is a methyl, phenyl or styryl radical and R1 is a saturated aliphatic hydrocarbon radical having from 1 to 8 carbon atoms. The compounds are prepared by reacting at an elevated temperature and under substantially non-oxidising conditions a b -furylidene ketone of the formula: <FORM:0948893/C2/2> in which R is as defined above with an excess of an anhydrous saturated aliphatic monohydric alcohol having from 1 to 8 carbon atoms in the presence of an anhydrous acid catalyst, and subsequently distilling the reaction mixture which is believed to contain an intermediate of the formula: <FORM:0948893/C2/3> to yield the desired product.  The reaction is preferably carried out in an inert atmosphere and in the presence of an antioxidant.  An organic solvent for the reactants may be present. The reaction may be conducted in a sealed tube. The desired products may be separated from the reaction mixture by distillation but when R represents a phenyl radical the reaction mixture is preferably first hydrogenated to increase the difference between the boiling points of the components of the mixture, only the starting material being hydrogenated to a lower boiling material.  In examples (1) b -furyl-acrylophenone and n-butanol are reacted together in the presence of hydrogen chloride to give butyl b -(2-(5-phenyl) furyl)-propionate which is purified by catalytic hydrogenation and fractional distillation and then saponified to the corresponding acid; (2) benzylidene-furylidene acetone and n-butanol with hydrogen chloride give butyl b -(2-(5-phenyl)-furyl)-propionate; (3) b -furyl-acrylophenone and iso-octanol with p-toluene sulphonic acid give isooctyl b -(2-(5-phenyl) furyl) propionate; (4) b -furylidene acetone and n-butanol with hydrogen chloride give butyl b -(2-(5-phenyl) furyl)-propionate.

Title: Preparation of acetals
Filed: 1947-12-08
Abstract: Acetals (including ketals) of dicarbonyl compounds of the general formula <FORM:0642830/IV (b)/1> are manufactured by reacting an a  : b -ethylenically-unsaturated ether <FORM:0642830/IV (b)/2> with an orthoester QC(OK)3 in the presence of an acid-reacting condensing agent (e.g. boron trifluoride or trichloride, stannic chloride, titanium chloride or sulphuric acid).  In the foregoing formul  R2, R3 and R4 represent hydrogen or an alkyl, aryl or aralkyl group, Q represents hydrogen or a hydrocarbon radical (preferably alkyl and especially lower alkyl), the K's represent radicals of an alcohol or phenol (e.g. aliphatic, aromatic or alicyclic radicals, including oxygen- or sulphur-interrupted aliphatic hydrocarbon radicals) or two of them in the orthoester may jointly represent a bivalent radical of a polyhydric alcohol, and n is an integer from 1-15, preferably 1-5. The process is applicable particularly to the production of malondialdehyde acetals from vinyl ethers and orthoformic esters, but there may also be used other a  : b -unsaturated ethers (e.g. the ethyl, methyl, n- and iso-propyl, isobutyl, dodecyl, phenyl, benzyl, vinyl, isopropenyl, b -methoxyethyl and b -methylthioethyl ethers of isopropenyl, butenyl and a - and b -phenylvinyl alcohols) and other orthoesters (e.g. the orthoacetates, orthobutyrates, orthobenzoates or orthophenylacetates of alcohols and phenols such as methyl, ethyl and propyl alcohol, the butyl alcohols, cyclohexanol, benzyl alcohol, phenylethyl alcohol, ethylene, propylene and butylene glycols, phenol and the cresols).  In examples: (1) methyl orthoformate is reacted with methyl vinyl ether in the presence of boron trifluoride-diethyl ether complex to produce malonaldehyde tetramethyl acetal; (2) ethyl orthoformate similarly yields malonaldehyde methyl triethyl acetal, together with compounds believed to be 1 : 1 : 3-triethoxy-5 : 5-dimethoxypentane and 1 : 1 : 3-triethoxy-5 : 7 : 7-trimethoxyheptane, and condensation products of 4-15 mols. of the ether with one of the orthoester; (3) ethyl orthoformate and divinyl ether are reacted as in (1) to form di-(1 : 3 : 3-triethoxypropyl) ether: (4) the methyl orthoformate in (1) is replaced by 2 - ethoxy - 1 : 3 - dioxolone, yielding 2 - (21 - methoxy-21-ethoxyethyl) - 1 : 3-dioxolone; (5) methyl orthoacetate similarly gives 1 : 1 : 3 : 3-tetramethoxybutane.  2 : 4-Dinitrophenylpyrazole is obtainable by heating 2 : 4 - dinitrophenylhydrazine with malonaldehyde tetramethyl acetal or di-(1 : 3 : 3-triethoxypropyl) ether in ethyl alcohol acidified with hydrochloric acid.
