SU389072A1 - METHOD OF MANUFACTURING OTHERRANGE Preparation of bisphenols by condensation of phenols with acetylene hydrocarbons. However, only phenyls of the dioxystilbene series and isopropyl'phenol dimers have been studied. The proposed method, based on a known reaction, allows one to obtain new compounds not described by IB - Google Patents

Description

40%) biophenol, t. Kip. 210-220 ° C / 5 mm, which is a mixture of isomers. Upon recrystallization of “C benzene, the p-isomer is obtained in the form of small crystals, mp. 143-144 ° C, yield 25%. Found,%: C 79.38; H 6.19; a pier weight 232. ClgH, 402. Calculated,%: C 79.6; H 6.2; a pier weight 226. The structure of .bi-sphenol is confirmed by an IR spectrometer. Example 2. Synthesis of 1,2-bys- (hydroxyphenyl) npotneHa-2. To 0.5 mol (47 g) of phenol and 2 g of sulfate of mercury At 50 ° C and vigorous stirring, 0.11 mol (6 g) of <RTI ID = 0.0> p-argyl </ RTI> alcohol is added and stirred for 2 hours at 50 ° C. The reaction products are isolated as in Example 1. Yield 20%. Example 3. Synthesis of 3-methyl-1,3-bys- (hydroxyphenyl) -butene-1. To 0.5 mol (47 g) of phenol and 1.5 g of boron etherate etherate 90 ° C and 0.1 mol (8.5 g) of dimethylethynyl 1 -ka1-carbonate in a mixture with 0.22 mol (20 g) of toluene are added with vigorous stirring and 0.5 mol (47 g) of phenol and ipath synthesis for 1.5 hours npHr90 ° C. The reaction product is isolated as in example 1, but bisphenol in the form of a fraction with m.p. 225-230 ° C / 5 mm. After recrystallization from benzene, the desired product is obtained in the form of white crystals, mp. 181 ° C. Yield 55%. Found,%: C 80.47; H 7.18; a pier .weight 256. Ci7Hi8O2. Calculated,%: C, 80.30; H 7.09; a pier weight 254. The structure of bisphenol is confirmed by IR-spectrum. Example 4. Synthesis of 4-methyl-2,4-bis- (oxnphenyl) -pent1-2. To 0.53 mol (50 g) of phenol and 50 g of the cation exchanger KU-2 at 90 ° C and vigorous stirring are added 0.1 mol (8.5 g) of dimethylethynylcarbinol mixed with 0.53 mol (50 g) of phenol and 0.22 mol (20 g) of toluene, replace the dropping funnel on a reflux condenser with a Dima-Stark trap and condense at the kinani temperature of the reaction mixture () for 5-6 hours to isolate the calculated amount of water. The products are separated from the catalyst, which is further washed with ether, and treated in the above manner. The yield of bisphenols 35% Example 5. Synthesis of 4-methyl-2,4-bms- (hydroxyphenyl) -pentene-2. To 0.585 mol (55 g) of phenol and 27 g of polyphosphoric ACID, at 50 ° C and vigorous stirring, add 0.075 mol of dimethylpropynylcarbynol mixed with 0.165 mol (15.5 g) of phenol and stirred for 1 hour at 50 ° C. The reaction products are isolated, as indicated above, and bisphenol is obtained in the form of a fraction with m.p. 218-226 ° C / 5 mm. Upon recrystallization from a mixture of benzene - hexane, pure bisphenol is obtained, so pl. 72 ° C. The yield is 27-30%. Found,%: C 80.39; H 7.22; a pier weight 264. Ci8H2O02. Calculated,%: C, 80.70; H 7.47; supposedly weight 268. The structure of bisphenol is confirmed by the IR spectrum. The subject of the invention 1. A method for producing double bond unsaturated bisphenols in a hydrocarbon bridge, characterized in that phenol is treated with acetylene alcohol in the presence of a catalyst — mercury sulfate or an acid catalyst, for example sulfuric acid, or a mixture thereof at 40-100 ° C followed by the selection of the target product known techniques. 2. A method according to claim 1, characterized in that the process is conducted in an environment of an organic solvent, for example benzene. 3. Method according to paragraphs. 1 and 2, characterized in that the process is carried out at a molar ratio between phenol and alcohol 2:: 1.
