Uses

Bisphenol TMC(1,1-Bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane) is a bisphenol derivative used in the preparation of polycarbonate, polyester and epoxy resins.

Synthesis

The synthesis of?1,1-BIS(4-HYDROXYPHENYL)-3,3,5-TRIMETHYLCYCLOHEXANE is as follows:112.8 g (1.2 mol) of phenol, 16.9 g of water, 0.5 g of 75% aqueous solution of phosphoric acid and 7.2 g of BPTMCP crystals were placed in a one liter capacity four-necked flask provided with a thermometer, a dropping funnel, a reflux condenser and a stirrer to prepare a slurry. The slurry was adjusted at a temperature of 20° C. After the inside the flask was replaced by nitrogen gas, hydrogen chloride gas was introduced into the flask under stirring. The gas composition in the reaction vessel was analyzed and the volume concentration of hydrogen chloride gas was adjusted at 80%. 4.2 g of 15% aqueous solution of sodium methyl mercaptide was added dropwise to the slurry while the slurry was maintained at a temperature of 20° C., and then a mixture of 112.8 g (1.2 mol) of phenol and 42.0 g (0.3 mol) of TMC was added dropwise to the slurry over a period of six hours. The reaction mixture was found to increase in temperature during the addition, and when the addition was completed, the temperature was found to be 40° C. Then, the reaction was further continued at a temperature of 40° C. for anther three hours under stirring until completion. The reaction mixture was found to be slurry throughout the reaction from the start of the reaction when the mixture of phenol and TMC was added dropwise to the slurry to the completion of the reaction. The resulting reaction mixture was analyzed by liquid chromatography. The production yield (mol of BPTMC produced/mol of starting TMC used) was found 92.9%.

Check Digit Verification of cas no

The CAS Registry Mumber 129188-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,8 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129188-99:
(8*1)+(7*2)+(6*9)+(5*1)+(4*8)+(3*8)+(2*9)+(1*9)=164
164 % 10 = 4
So 129188-99-4 is a valid CAS Registry Number.

Page/Page column 4, (2010/02/12)

A method of producing 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane comprising: crystallizing a phenol adduct of 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane from a solution comprising 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane and phenol; washing the phenol adduct with a washing solution comprising phenol and water; decomposing by heating the washed phenol adduct in an aqueous solvent to remove phenol from the phenol adduct, thereby obtaining pure 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane.

Method for producing 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane

-

Page column 8-10, (2010/02/05)

The invention provides a process for production of high purity 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane (BPTMC) which comprises: (a) a reaction step wherein phenol is reacted with 3,3,5-trimethylcyclohexanone (TMC) in a slurry containing phenol adduct crystals of BPTMC in the presence of an acid catalyst; (b) a neutralization step wherein after the reaction, the resulting reaction mixture in the form of slurry is neutralized with an alkali while heating to convert the slurry to a solution; (c) a primary crystallization and filtration step wherein the resulting solution is cooled and the resulting phenol adduct crystals of BPTMC are collected by filtration; (d) a secondary crystallization and filtration step wherein the adduct crystals obtained in the primary crystallization and filtration step are heated in a crystallization solvent to dissolve the crystals therein to prepare a solution and then the solution is cooled to crystallize BPTMC out of the solution, followed by collecting the crystals of BPTMC by filtration; (e) a filtrate recycling step wherein at least a part of the secondary crystallization filtrate obtained in the secondary crystallization and filtration step is returned to the reaction step. The process provides uncolored high purity BPTMC in high selectivity and in high yield in an industrially stable manner which is substantially free from residual phenol and trace impurities such as sodium, chlorine and sulfur and hence which is suitable for use as raw materials for the production of resins for optical use.
