Read： 479 Time：20months ago Source：Transform the World with Simplicity

Methoxyflurane is a commonly used chemical raw material, widely used in medicine, pesticides, dyes and other fields. A common manufacturing method of methoxyflurane will be described below.

1. raw materials and equipment

1. raw materials: methanol, hydrofluoric acid, sulfuric acid.
2. Equipment: reactor, condenser, separatory funnel, distillation unit.

2. Manufacturing Steps

1. Add methanol and hydrofluoric acid into a reactor according to a certain ratio and stir evenly.
2. While stirring, slowly add sulfuric acid to adjust the pH of the reactor to the specified range.
3. Heat the reactor to allow the mixture to react at a certain temperature for a certain period of time.
4. After completion of the reaction, the reaction mixture was cooled to room temperature, and unreacted methanol and water were separated by a separating funnel.
5. The organic phase is collected and distilled by a distillation device to collect the product of the specified fraction, namely methoxyflurane.
Precautions for
3.

1. Strictly control the proportion of raw materials and the addition speed to ensure the smooth progress of the reaction.
2. When adjusting the pH value, pay attention to the speed and amount of sulfuric acid to avoid corrosion of the equipment caused by over-acid or over-alkali.
3. In the heating process, the reaction temperature and time should be controlled to avoid the decomposition of methoxyflurane.
4. During the distillation process, the distillation temperature and vacuum degree should be controlled to ensure that the purity of the collected methoxyflurane meets the requirements.

4. safety and environmental protection

1. During the operation, pay attention to protect the health of the operator and avoid contact with toxic and harmful substances.
2. Waste should be properly disposed of to avoid environmental pollution.
3. The production process should follow the relevant safety procedures to ensure production safety.

In short, the manufacture of methoxyflurane requires strict control of raw materials, equipment, manufacturing steps, safety and environmental protection requirements to ensure product quality and production safety. At the same time, production enterprises should strengthen the training and management of employees, improve their operational skills and safety awareness, and ensure the smooth progress of the manufacturing process of methoxyflurane.
