The client who is going to conduct the experiment today is in the pharmaceutical industry. The material used is Vaseline, and the equipment required for salicylic acid is a 1L reaction kettle, water bath, vacuum pump, and emulsifier

.

The experiment has started: First, weigh the materials according to the proportion and add them to our reaction kettle in sequence. Press the power button to start the equipment running and match it with the water bathHeat to melt, temperature controlled at

Add finely ground salicylic acid powder into melted Vaseline at around 60 ℃, stirring while adding, until a uniform and delicate ointment is formed.

The Ouhe AIR-1S reactor has the following functions:

1. Mixing system: used to achieve uniform mixing of reactants. Experimental vacuum reactors are usually equipped with multiple types

Types of mixers, such as paddle type, anchor type, screw type, etc., to meet the mixing needs of different materials.

2. Sealing device: It is an important component of the experimental vacuum reactor, using advanced sealing technologies such as mechanical seals, magnetic seals, etc. to ensure that the reactor body is in a vacuum or pressure state

Maintain good sealing performance under normal conditions to prevent the leakage of reactants and the entry of external impurities.

3. Vacuum system: A vacuum environment helps to lower the boiling point of reactants, increase reaction rate, reduce the occurrence of oxidation and hydrolysis reactions, and improve product purity and yield

4. Emulsification system: The principle of emulsification system is based on the amphiphilic properties of surfactants. Change the interface state so that liquids that cannot be mixed can be mixed.
