Description of PPH Propylene glycol Phenyl Ether: 

Physical property

Appearance: PPH is a colourless to light yellow transparent liquid with a special odour.

Melting point: PPH has a low melting point, usually below -30°C, showing good fluidity.

Boiling point: PPH has a high boiling point, about 250°C, and is not volatile.

Solubility: PPH can be dissolved in most organic solvents, such as alcohols, ethers, esters, etc., but insoluble in water.

Stability: PPH is relatively stable at room temperature, but decomposition or oxidation may occur under high temperature, strong acid, strong base and other conditions.

Chemical properties

Acid alkaline: PPH has a certain acidity and can be used as an acid catalyst. In addition, it also has a low corrosion and less impact on metal materials.

Reactivity: PPH can participate in a variety of chemical reactions, such as esterification, etherification, alkylation, etc. It is a commonly used organic synthesis intermediate for the synthesis of a variety of organic compounds.

Oxidation: Under certain conditions, PPH may undergo oxidation reactions to produce corresponding oxidation products. Therefore, care needs to be taken to prevent prolonged exposure to air or contact with oxidants during storage and use. Safety and toxicity

Toxicity: PPH has certain toxicity, and long-term exposure may cause harm to the human body. Therefore, appropriate protective measures should be taken during use, such as wearing personal protective equipment such as gloves and masks.

Safety: Because PPH has a certain risk, it is necessary to follow the relevant safety specifications during storage and use. PPH should be stored in a cool, well-ventilated place away from fire and heat sources. At the same time, during use should avoid contact with the skin and eyes, if accidentally contact the skin or eyes, should immediately rinse with plenty of water and medical treatment.

It can effectively dissolve and remove grease, oil, and other impurities, to achieve the purpose of cleaning and degreasing. In the field of industrial production and maintenance, PPH is widely used in metal surface treatment, mechanical parts cleaning, electronic equipment cleaning, and other aspects. In addition, PPH can be combined with other ingredients to form efficient, environmentally friendly cleaning agents and degreasing agents to meet the needs of different sectors.

Production Method of PPH Propylene glycol phenyl ether:

Chemical synthesis

Chemical synthesis is a common method to produce propylene glycol phenyl ether. The method converts the raw material into the target product through chemical reactions. The following are the specific steps of chemical synthesis:

Preparation of raw materials: Prepare the required raw materials, such as phenol, propylene glycol, and sulfuric acid. These raw materials should meet the specifications to ensure the quality of the propylene glycol phenyl ether produced.

Esterification reaction: phenol and propylene glycol are added to the reactor, and an appropriate amount of sulfuric acid is added as a catalyst. The reaction of phenol and propylene glycol to propylene glycol phenyl ether was carried out under a certain temperature and pressure.

Separation and purification: The generated propylene glycol phenyl ether is separated and purified after the reaction. Usually, the products are separated by distillation, crystallization, and other methods and then refined and dried to obtain high-purity propylene glycol phenyl ether.

Product testing and quality control: The propylene glycol phenyl ether produced shall be tested and controlled to ensure it meets relevant standards and customer requirements.

The advantages of chemical synthesis are a mature process, high yield, and strong applicability. The molecular weight and other properties of propylene glycol phenyl ether can be controlled by adjusting the reaction conditions and the ratio of raw materials. In addition, the chemical synthesis method can adopt continuous production, which reduces production costs and improves production efficiency.

However, there are some challenges and limitations to chemical synthesis. First, the esterification reaction requires the use of sulfuric acid as a catalyst, which has a corrosive effect on the equipment and is not environmentally friendly. Second, the process requires using toxic raw materials, such as phenol, so there are safety risks and environmental issues. Therefore, corresponding measures need to be taken in actual production to control these negative effects.

Direct esterification method

Direct esterification is a relatively simple method to prepare propylene glycol phenyl ether. The method directly esterified phenol and ethylene oxide to produce propylene glycol phenyl ether, avoiding using sulfuric acid as a catalyst and toxic raw phenol. The following are the specific steps of the direct esterification process:

Add phenol and ethylene oxide to the reactor and stir well.

The phenol and ethylene oxide reaction to propylene glycol phenyl ether was carried out at a certain temperature and pressure.

After the reaction, the propylene glycol phenyl ether was separated and purified. Usually, the products are separated by distillation, crystallization, and other methods and then refined and dried to obtain high-purity propylene glycol phenyl ether.

The advantages of direct esterification are that it is simple to process, safe, and has environmental protection. The method avoids using sulfuric acid as a catalyst and toxic raw material phenol and reduces the corrosion of the equipment and the impact on the environment. In addition, ethylene oxide, the raw material used in the direct esterification process, is relatively easy to obtain, reducing production costs.
