(2) Reaction Into a 100 ml content autoclave, 2.0 grams of zeolite prepared as above and 2.0 grams of tetracyclo-(6.2.1.13,6.02,7) dodecane were placed quickly and after evacuation hydrogen chloride gas was introduced to 1.5 kg/cm2 followed by hydrogen gas to total pressure of 30 kg/cm2. The reaction was carried out for 4 hours at 250 C. with stirring. After the reaction, n-tridecane was added to the reaction mixture and then the catalyst (zeolite) and the reaction solution was separated by filtration. The reaction solution was analyzed using p-cymene as the internal standard by gas chromatography. As the result, conversion yield of tetracyclo-(6.2.1.13,6.02,7) dodecane, selectivity of 1,3-dimethyl adamantane, yield of 1,3-dimethyl adamantane, selectivity of 1-ethyl adamantane, and yield of 1-ethyl adamantane were 21.5%, 9.3%, 2.0%, 15.2% and 3.3%, respectively. |

77%; 15% | With hydrogen fluoride; boron trifluoride; at 100℃; for 4h;Autoclave; | Example 1 [0040] PHA was subjected to an isomerization reaction by use of a Hastelloy autoclave having a capacity of 0.5 L and including an electromagnetic stirring device, a heating device, a gas and liquid supply opening and a reaction product discharge opening. 50 g (2.5 mol) of HF produced by Morita Chemical Industries Co., Ltd. and 100 g (0.6 mol) of PHA were put to a reactor, and 16 g (0.24 mol) of BF3 produced by Stella Chemifa Corporation was supplied. Then, these substances were heated to a temperature of 100 C. by the heating device with no solvent, and stirred for 4 hours while the temperature was kept at 100 C. The reaction product solution was sampled. The yield of 1,3-dimethyladamantane was 77% with respect to PHA as the material. The yield of 1-ethyladamantane as an intermediate was 15% with respect to PHA as the material, while no high boiling point compound was observed. Then, as a result of being left still, the reaction product solution was divided into two layers, namely, an organic layer containing 1,3-dimethyladamantane and a catalyst layer. The catalyst layer was obtained by liquid-liquid separation. The separated catalyst layer was supplied to a distillation tower in which heptane was circulated. As a result, almost all the amount of BF3 was recovered from a top part of the tower, and almost all the amount of HF was recovered from a condenser in the top part of the tower. |
