Ребят помогите , пожалуйста это очень важная работа по химии, буду очень благодарен)

 

 

Получение карбоновых кислот

Окисление альдегидов.
В промышленности: 2RCHO + O2 2RCOOH

В лаборатории с помощью окислителей: Ag2O, Cu(OH)2, KMnO4, K2Cr2O7 и др. Окисление спиртов: RCH2OH + O2 RCOOH + H2O Окисление углеводородов: 2C4H10 + 5O2 4CH3COOH + 2H2O Из солей (лабораторный способ):

            CH3COONaкр. + H2SO4 конц. CH3COOH + NaHSO4

  5.   Для отдельных кислот существуют специфические спосо­бы получения. Муравьиную кислоту получают нагреванием оксида углерода (II) с порошкообразным гидроксидом натрия под давлением и об­работкой полученного формиата натрия сильной кислотой:

 

200 °С, Р

 

H2SO4

 

NaOH + СО

HCOONa

НСООН

Домашнее задание.

Задача 1. Осуществить следующие превращения: этан → бромэтан→бутан →   уксусная кислота → хлоруксусная кислота? Напишите уравнения реакций.

Задача 2. Определите массу сложного эфира, который можно получить при взаимодействии 92 г этилового спирта и 100 г уксусной кислоты.

Задание 1

C2H6 =C2H5Br =C4H10 = CH3COOH =CH2ClCOOH

1.C2H6 + Br2 = C2H5Br + HBr

2.2C2H5Br + 2Na =C4H10 +2NaBr.

3.2C4H10 + 5O2 = 4CH3COOH + 2H2O

4.CH3COOH + Cl2 =CH2ClCOOH + HCl

Второе сама незнаю :(
