How to get formic acid from acetic acid ?

Answer 1

How about this?

Step 1. Reduction with #"LiAlH"_4#
#"CH"_3"COOH" stackrelcolor(blue)("1. LiAlH"_4"; 2. H"^"+"color(white)(mm))(→) "CH"_3"CH"_2"OH"#

Step 2. Dehydration

#"CH"_3"CH"_2"OH" stackrelcolor(blue)("H"_2"SO"_4, Δcolor(white)(mm))(→) "H"_2"C=CH"_2#

Step 3. Ozonolysis

#"H"_2"C=CH"_2 stackrelcolor(blue)("1. O"_3"; 2. Zn/H"_2"O"color(white)(mm))(→) "2H"_2"C=O"#

Step 4. Oxidation

#"HC(=O)H" stackrelcolor(blue)("H"_2"O"_2, "Fe"^"2+"color(white)(mm))(→) "HC(=O)OH"#

Answer 2

Formic acid can be obtained from acetic acid through various methods, one of which involves oxidation. Here's a general outline of the process:

  1. Oxidation: Acetic acid can be oxidized to formic acid using a suitable oxidizing agent, such as potassium permanganate (KMnO4) or chromic acid (H2CrO4). The reaction typically occurs in the presence of a catalyst, such as sulfuric acid (H2SO4).

  2. Reaction conditions: The reaction is usually carried out under controlled conditions of temperature and pressure to ensure efficient conversion of acetic acid to formic acid.

  3. Isolation: After the oxidation reaction is complete, the formic acid is isolated from the reaction mixture. This can be done through processes such as distillation or extraction.

  4. Purification: The isolated formic acid may undergo further purification steps to remove impurities and obtain a high-purity product.

Overall, the process involves oxidizing acetic acid to formic acid under controlled conditions, followed by isolation and purification of the formic acid product.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
