production example 1
[Preparation of Alkylphenol (a)]
[0169] A reactor equipped with a baffle and a stirrer was charged with raw materials and a catalyst in a proportion of 300 mass parts of phenol, 110 mass parts [phenol / olefin=9 / 1 (mole ratio)] of 1-docosene and 11 mass parts of a strong acid polystyrene base sulfonic acid type cation exchange resin (Amberlyst 15, manufactured by Rohm & Haas Co., Ltd.) as the catalyst to carry out reaction at 120° C. for 3 hours under stirring.
[0170] After finishing the reaction, the reaction mixture was refined by distillation under reduced pressure to obtain alkylphenol (a). An alkyl group of the alkylphenol (a) thus obtained had 22 carbon atoms.
production example 2
[Production of PC Oligomer]
[0171] Bisphenol A 60 kg was dissolved in 400 liter of a 5 mass % sodium hydroxide aqueous solution to prepare a sodium hydroxide aqueous solution of bisphenol A.
[0172] Then, a tubular type reactor having an inside diameter of 10 mm and a tube length of 10 m was charged with the above sodium hydroxide aqueous solution of bisphenol A maintained at a room temperature at a flow rate of 138 liter / hour and methylene chloride at a flow rate of 69 liter / hour through an orifice plate, and phosgene was blown thereinto in a parallel current at a flow rate of 10.7 kg / hour to continuously react them for 3 hours.
[0173] The tubular type reactor used above had a double tube structure, and cooling water was allowed to pass through a jacket part to maintain a discharge temperature of the reaction liquid at 25° C. A pH of the reaction liquid was controlled to 10 to 11.
[0174] The reaction liquid thus obtained was left standing still to thereby separate and remove an aqueo...

[Production of Reactive Polydimethylsiloxane (PDMS)]
[0176] Octamethylcyclotetrasiloxane 1,483 g was mixed with 18.1 g of 1,1,3,3-tetramethyldisiloxane and 35 g of 86% sulfuric acid, and the mixture was stirred at a room temperature for 17 hours.
[0177] Then, the oil phase was separated, and 25 g of sodium hydrogencarbonate was added thereto, followed by stirring the mixture for one hour. After filtration, the filtrate was subjected to vacuum distillation at 150° C. and 3 torr (4×102 Pa) to remove low boiling matters, whereby an oily matter was obtained.
[0178] The oily matter 294 g obtained above was added to the mixture of 60 g of 2-allylphenol and 0.0014 g of platinum having the form of a platinum chloride-alcolate complex at a temperature of 90° C.
[0179] The above mixture was stirred for 3 hours while maintaining at a temperature of 90 to 115° C.
[0180] The resulting product was extracted with methylene chloride and washed three times with aqueous methanol of 80% to remove exces...
