WitrynaAnswer. Exercise 2. When 1.000 g of a certain triglyceride (fat) is treated with hydrogen gas in the presence of Adams’ catalyst, it is found that the volume of hydrogen gas consumed at 99.8 kPa and 25.0°C is 162 mL. A separate experiment indicates that the molar mass of the fat is 914 g mol −1. Witrynaportionation and alkylation (Table 6.1.III) are again typical zeolite-catalyzed processes which result from shape-selective catalysis in the proton-decorated micropores of certain zeolites (see below and in other chapters). In Tables 6.l.IV and 6.1.V technology for the synthesis of substrates which contain heteroatoms has been collected.
