1)СН4+Сl2=CH3Cl+HCl
2)2CH3Cl+Na=C2H6+NaCl
2.Получение пропана из этана происходит в две реакции.
1)С2Н6 + Cl2 = C2H5Cl + HCl
2)C2H5Cl + CH3Cl + 2Na = C3H8 + 2NaCl.
3.Получение гексана из пропана происходит в две реакции.
1)С3Н8+Cl2=C3H7Cl+C3H7Cl+2HCl
2)2C3H7Cl+2Na=C6H14+2NaCl
4.В процессе ароматизации нефтепродуктов и каталитического риформинга гексан дегидроциклизуется в бензол.
C6H14=C6H6 + 4H2
5.Получение нитробензола из бензола(реакция нитрования).
C6H6 + HNO3=C6H5NO2
Для приготовления одного моля NH₄NO₃, потребуется 1 моль NH₃
М (NH₃) = 14 + 3 = 17 г/моль
М (NH₄NO₃) = 14 + 4 + 14 + 48 = 80 г/моль
Теоретически для приготовления 1 моль * 80 г/моль = 80 г NH₄NO₃ потребуется 1 моль * 17 г/моль NH₃, тогда для приготовления 8 т NH₄NO₃, потребуется х т NH₃. Найдём х:
х = 8 * 17 / 80 = 1,7 т
Так как Выход продукта составляет 80 % от теоретически возможного, значит:
m (NH₃) = 1,7 / 0,8 = 2,125 т
ответ для получения 8 тонн нитрата аммония, потребуется 2,125 т аммиака
