1. Chemical Structure and Properties. HCOOCH₃ + CH₃CH₂OH
🔹 Methyl Formate (HCOOCH₃)
- IUPAC Name: Methyl methanoate
- Structure: H–C(=O)–O–CH₃
- Type: Ester
- Appearance: Colorless liquid with a pleasant odor
- Boiling Point: ~31.5°C
🔹 Ethanol (CH₃CH₂OH)
- IUPAC Name: Ethanol
- Structure: CH₃–CH₂–OH
- Type: Alcohol
- Appearance: Clear, colorless liquid with a distinctive alcohol smell

2. The Reaction Between HCOOCH₃ and CH₃CH₂OH.
When methyl formate (HCOOCH₃) reacts with ethanol (CH₃CH₂OH), the reaction can be categorized as transesterification under acidic or basic conditions. In such reactions, one ester reacts with an alcohol to form a new ester and a different alcohol.
General Reaction (Transesterification):
HCOOCH₃ + CH₃CH₂OH → HCOOCH₂CH₃ + CH₃OH
(Methyl formate + Ethanol → Ethyl formate + Methanol)
3. Mechanism of the Reaction. HCOOCH₃ + CH₃CH₂OH
This reaction typically requires an acid or base catalyst to proceed efficiently. Here’s a simplified version of the acid-catalyzed mechanism:
- Protonation of the Ester: The ester oxygen in methyl formate is protonated by the acid catalyst.
- Nucleophilic Attack: Ethanol attacks the carbonyl carbon of the ester.
- Intermediate Formation: A tetrahedral intermediate forms.
- Exchange of Alkoxy Groups: The original methoxy group (–OCH₃) leaves, forming methanol.
- Deprotonation: The newly formed ethyl formate is deprotonated.

4. Products and Their Uses
🔹 Ethyl Formate (HCOOCH₂CH₃)
- Used as a solvent for cellulose nitrate and other resins
- Has a rum-like odor, used in flavorings and perfumes
- Acts as an intermediate in organic synthesis
🔹 Methanol (CH₃OH)
- Used as an industrial solvent
- Important in formaldehyde and acetic acid production
- Used in fuel blending and antifreeze solutions
5. Real-Life Applications. HCOOCH₃ + CH₃CH₂OH
- Industrial Organic Synthesis: Transesterification reactions like this are foundational in organic chemistry labs and industries.
