It is desired to prepare polyester with the number average molecular weight, Mn 5000 g/mol by reacting of 1 mol butane-1,4 diol (HO-CH-CH2-CH2-CH2-OH) with 1 mol of adipic acid (HOOC-CH2-CH2-CH2-CH2-COOH) (a) Write chemical equation illustrating synthesis of the polyester. (b) Calculate the value of the monomer conversion at which the reaction should be stopped to obtain this polymer, assuming perfect stoichiometric balance. What would be polydispersity index for the polymer obtained? (c) Assuming that 0.5 mol % of the diol...

1. Acrylonitrile is produced by the reaction of propylene, ammonia, and oxygen C3H6 + NH3 + O2 C3H3N + 3H2O The feed contains 10 mole% propylene, 12% ammonia, and 78% air. A fractional conversion of 30% of the limiting reactant is achieved. Determine which reactant is limiting, the percentage by which each of the other reactants is in excess, and the molar flow rates of all product gas constituents for a 30% conversion of the limiting reactant, taking 100...

8) Ethylene oxide is produced by the catalytic oxidation of ethylene. C2Ha(g)+1/202(g) C2H4O(g) An undesired competing reaction is the combustion of ethylene to CO2. The feed to a reactor contains 2 mol C2H4/mol O2. The conversion in the reactor is 25% , and 0.70 mol of CaHeO is produced per mol of C2H4 consumed. A multiple- unit process is used to separate the products: C2H4 and O2 are recycled back to the reactor, C2H4O(g) is produced as a product (at...
