Question

Составьте уравнения реакций,при помощи которых можно получить альдегиды и кетоны

Answer 1

Получение формальдегида: 2CH3OH + O2 (катализ. - медь, 300 град. ) = 2СH2O + 2H2O,
CH4 + O2 (катализ. - оксиды азота, 500 град) = CH2O + H2O.
Получение ацетальдегида: 2C2H4 + O2 (катализ - смесь PbCl2, Cu2Cl2, давлен, температ. ) = 2CH3COH.
Получение диметилкетона: 2C2H2 + 3H2O (катализ. - оксиды железа и марганца, 450 град) =
CH3-CO-CH3 + 2H2 + CO2.

Forming Equations for the Production of Aldehydes and Ketones

To form aldehydes and ketones, various reactions can be used. Here are some equations for the production of aldehydes and ketones:

1. Oxidation of Primary Alcohols to Aldehydes: - The oxidation of primary alcohols can yield aldehydes. - Equation: ``` R-CH2OH + [O] → R-CHO + H2O ``` Source: 2. Oxidation of Secondary Alcohols to Ketones: - The oxidation of secondary alcohols can yield ketones. - Equation: ``` R2-CHOH + [O] → R2-CO + H2O ``` Source: 3. Ozonolysis of Alkenes: - Ozonolysis of alkenes can produce aldehydes and ketones. - Equation: ``` R-CH=CH-R' + O3 → R-CHO + R'-CHO ``` Source: 4. Hydroboration-Oxidation of Alkenes: - Hydroboration-oxidation of alkenes can yield aldehydes and ketones. - Equation: ``` R-CH=CH2 + Sia2BH → R-CH2-CH2-BH2 R-CH2-CH2-BH2 + H2O2, -OH → R-CHO + H3BO3 ``` Source: 5. Friedel-Crafts Acylation: - Friedel-Crafts acylation can be used to produce ketones. - Equation: ``` R-X + R'C(O)Cl → R-C(O)-R' + HCl ``` Source: 6. Clemmensen Reduction: - Clemmensen reduction can be used to reduce ketones to alkanes. - Equation: ``` R-C(O)-R' + Zn(Hg), HCl → R-CH2-R' ``` Source: These are some of the reactions that can be used to produce aldehydes and ketones. Each reaction has its own specific conditions and mechanisms for the formation of these functional groups.
