Methyl Propylene Glycol Properties
Methyl propylene glycol (Methylenediol), molecular formula C4H8O2, is a transparent, colorless liquid with a faint alcohol odor. It has a boiling point of about 210°C and a density of 1.03g/cm³. It has good solubility and is miscible with water and many organic solvents. Methyl propylene glycol has high chemical stability, but decomposition or polymerization may occur under high temperature or acid-base conditions. Because of its low volatility and high boiling point, methyl propylene glycol has high safety during use and is not easily volatilized into the air to cause pollution.
Methyl propylene glycol use
Methyl propylene glycol is widely used in industry. One of its main uses is as a solvent and intermediate in the production of coatings, inks and resins. It not only provides excellent solubility in coatings and inks, but also improves the drying speed and adhesion of the product. Methyl propylene glycol is also an important polymer monomer and is widely used in the production of polyester resins and polyurethanes. It can also be used as a moisturizer and thickener in cosmetics and personal care products, and is popular due to its low toxicity and good skin compatibility.
Upstream raw materials
The production of methyl propanediol relies primarily on several key upstream feedstocks. The first is methacrolein (Methacrolein), which is one of the main precursor compounds for the production of methylpropanediol. Methacrolein can be converted to methyl propylene glycol by catalytic hydrogenation. Acrylic acid (Acrylic Acid) and formaldehyde (Formaldehyde) are also important raw materials for the production of methylpropanediol, which can be efficiently converted through a series of complex chemical reactions. Therefore, the market supply and price of methylpropanediol is largely affected by the market fluctuations of these upstream feedstocks.
Downstream Products
The downstream products of methyl propylene glycol are diverse, mainly including coatings, inks, resins and cosmetics. In the coatings industry, methyl propylene glycol is used to produce high-performance polyester resin and polyurethane coatings, which have excellent weather resistance and adhesion. In the ink production, methyl propylene glycol can provide good fluidity and fast drying performance, is an important component of high quality printing ink. In the resin industry, methyl propylene glycol is used to produce a variety of resin materials, such as epoxy resin, acrylic resin, etc., and is widely used in construction, automotive and electronics industries. In cosmetics and personal care products, methyl propylene glycol is used as a humectant and thickener in a variety of skin care and hair products.
Production process
The production process of methyl propylene glycol mainly includes several key steps. The first is the preparation and pretreatment of raw materials, such as the synthesis and purification of methacrolein. This is followed by a catalytic hydrogenation reaction to convert methacrolein to methylpropanediol, which is usually carried out at high temperature and pressure and requires the use of a specific catalyst. This is followed by the separation and purification of the product, and the removal of impurities through distillation and other processes to obtain high-purity methyl propylene glycol. Finally, the packaging and storage of the product to ensure its stability and safety during transportation and use.
storage method
The storage of methyl propylene glycol requires attention to several key factors. Because it is sensitive to moisture and oxygen, the storage container must be well sealed to prevent the ingress of air and moisture. The appropriate storage temperature is a cool and dry place at room temperature, avoiding direct sunlight and high temperature environment. The material of the storage container shall be corrosion-resistant metal or plastic to ensure that corrosion and leakage of the container will not occur during long-term storage. The storage area should be well ventilated to prevent safety incidents due to the accumulation of volatile gases.
