1-methoxy-2-propanol, with the CAS number 107-98-2, is a colorless, flammable liquid with a mild, ether-like odor. It is also known as propylene glycol methyl ether. The molecular formula of 1-methoxy-2-propanol is C4H10O2, and its molecular weight is 90.12 g/mol. The boiling point of this product is around 118 - 119 °C, and the melting point is -97 °C. It has a density of approximately 0.923 g/cm³ at 20 °C. This product is miscible with water and many organic solvents, which makes it a very useful solvent in various industries.
1-methoxy-2-propanol has a wide range of applications. In the paint and coating industry, it is used as a coalescing agent. It helps the paint to form a uniform film by softening and fusing the paint particles together. This results in a smoother and more durable finish. In the printing ink industry, it is used as a solvent to adjust the viscosity of the ink, ensuring good printability and drying performance. In the cleaning agent industry, it can dissolve grease, oil, and other contaminants, making it an effective ingredient in industrial and household cleaners. It is also used in the production of electronic chemicals, such as in the manufacturing of printed circuit boards, where it helps to clean and etch the boards.
When using 1-methoxy-2-propanol, proper safety precautions should be taken. Always wear appropriate personal protective equipment, including gloves, safety glasses, and a lab coat. Work in a well - ventilated area or use local exhaust ventilation to prevent the inhalation of vapors. When handling the product, avoid contact with skin and eyes. In case of skin contact, immediately wash the affected area with plenty of water for at least 15 minutes. If inhaled, move to an area with fresh air. If ingested, do not induce vomiting and seek medical attention immediately. When using it as a solvent in a formulation, follow the recommended dosage and mixing procedures provided by the manufacturer. The product can be added to the formulation in a step - by - step manner while stirring to ensure uniform mixing.
Case 1: Paint Coating Application
A paint manufacturer was facing issues with the film formation of their water - based paints. After adding 1-methoxy-2-propanol as a coalescing agent at a concentration of 5% by weight, they noticed a significant improvement in the paint's film formation. The paint dried faster and formed a more uniform and glossy finish. The paint also showed better adhesion to the substrate, which increased its durability.
Case 2: Printing Ink Industry
A printing company was having problems with the viscosity of their inks, which was affecting the print quality. By using 1-methoxy-2-propanol as a solvent to adjust the ink viscosity, they were able to achieve the optimal viscosity range. This led to sharper and more accurate prints, with reduced smudging and bleeding. The drying time of the ink was also reduced, increasing the overall printing efficiency.
Case 3: Cleaning Agent Production
A household cleaning product manufacturer incorporated 1-methoxy-2-propanol into their all - purpose cleaner. The product showed excellent cleaning performance on various surfaces, including countertops, floors, and appliances. It was able to dissolve stubborn grease and stains effectively, leaving the surfaces clean and shiny. The product also had a pleasant odor, which was well - received by consumers.
