Propylene Glycol Methyl Ether (PM; CAS No. The use of glycol ethers has changed significantly over the past 30 years. Process according to claim 4 or 5, wherein the article is soaked with said solvent for 5 to 45 minutes. With PM, the results were between those of water and chlorine type solvents. Tetramethylguanidine-based ionic liquids were used as effective catalysts for the synthesis of propylene glycol methyl ether from methanol and propylene oxide. It finds use as a less volatile alternative to propylene glycol methyl ether and other glycol ethers. 1,1,1-Trichloroethane and perchloroethylene, which have been used in the prior art as solvents for dry cleaning, have the problem of polluting underground water, while some kinds of chlorofluorcarbons have the problem of destroying the ozone layer, and therefore there is currently a great need for rapid investigation of alternative substances. Propylene glycol methyl ether acetate, .alpha.-isomer / PGMEA / 1-Methoxypropan-2-yl acetate / Acetic acid, 2-methoxyisopropyl ester / 1-Methoxypropan-2-ol acetate 1.2. Eastman™ PM Solvent (Propylene Glycol Monomethyl Ether), a medium-boiling glycol ether, is an active solvent for cellulose acetate butyrate, nitrocellulose, epoxy, phenolic, acrylic, and alkyd resins. This test was conducted by piling 4 sheets of cotton cloths of 5 x 5 cm, adding by drops 0.125 g of each solvent and measuring the vaporization rate of the solvent. Similar to other glycol ethers, it is used as a carrier/solvent in printing/writing inks and paints/coatings. Synonym: 1,2-Propanediol monomethyl ether acetate, 1-Methoxy-2-propyl acetate, MPA, PGMEA, Propylene glycol methyl ether acetate Linear Formula: CH … More specifically, detergency is measured according to "solubility" and "dispersibility" of various types of soil, including oil-soluble soils such as skin fat, fat and oil, oil mist, etc. In the dry cleaning process, if a long time is required for the drying of the article to be washed, work efficiency will be markedly lowered. Use according to claim 1, wherein water is present in a concentration of 0.4 to 50 vol.% of the solvent. Propylene glycol monomethyl ether. Related Pages. (5) There is no corrosion of cleaning machine, etc. Water, perchloroethylene, 1,1,1-trichloroethane, CFC-113 and PM were each employed as solvent, a distillation residue of a cleaning factory was used as the oil-soluble soil and instant coffee powder as the water-soluble soil solutes. Propylene Glycol Methyl Ether Acetate / Propylene Glycol Monomethyl Ether Acetate cas 108-65-6 . Propylene glycol monomethyl ether is relatively low in toxicity. 20400/1988), solvent for floor use (Japanese Unexamined Patent Publications Nos. All rights reserved. use restrictions (moderate) solvent. 3: 627-630. (Ref. The desorption behavior of propylene glycol monomethyl ether acetate (PGMEA), which is a volatile organic compound (VOC) used in semiconductor manufacturing, from activated carbon (AC) was experimentally and theoretically studied over a wide range of supercritical carbon dioxide (scCO 2) conditions at T=(313 K to 353 K) and P=(10.0 MPa to 20.0 MPa) for the design of AC regeneration … The PM of the present invention has the following advantages when used as a solvent for dry cleaning: Use of a solvent consisting of propylene glycol monomethyl ether and water for dry cleaning. It is frequently used as a substitute for the more toxic DEGME (diethylene glycol methyl ether). In the case of 1,1,1-trichloroethane, perchloroethylene, when the water in the article to be washed mixes with the solvent, the water cannot be hydrated with the solvent and may cause the article to shrink, but PM will not give rise to such shrinkage, as shown in Table 3. The sol is hydrophilic, and therefore firmly adheres onto cotton, having a hydrophilic surface. Propylene Glycol Monomethyl Ether 107-98-2,1_OKCHEM. T3, Free format text: ; water-soluble soils such as sweat, water-soluble foods; dirts such as sludge, dust, etc., the degree of "counter-contamination", that is, soil washed from clothing migrating back from the cleaning liquid to the clothing, and the degree of small surface tension of the solvent penetrating into the clothing and between the soils. In other words, while the chlorine type solvents of the prior art use soap to aid in dissolving performance for water-soluble soils, PM exhibited good detergency for water-soluble soils on its own. It is used in a variety of coating, printing ink, and cleaning applications. It is used in a variety of coating, printing ink, and cleaning applications. Fischer 344 rats (10/sex/group) and New Zealand White rabbits (7/sex/group) were exposed to 0, 300, 1000, or 3000 ppm propylene glycol monomethyl ether (PGME) (1106, 3686, or … The test was conducted by immersing and stirring a cloth strip of 2.5 x 2.5 cm in 75 ml of a solvent containing each solute dissolved therein, and soaking it for 5 minutes.

The results compared the vaporization rates of the respective solvents with that of perchloroethylene (1) as shown in Table 4. On the other hand, dyeability was great with water. B1, Ref document number: S Similar to other glycol ethers, it is used as a carrier/solvent in printing/writing inks and paints /coatings. On the other hand, in water and PM the oil floated like a sol in the solution and since the sol is lipophilic it adhered onto the wool and polyester which have lipophilic surfaces. In a chlorine type solvent counter-contamination on wool and cotton was marked, while the results with water were good.
