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 (PM; CAS No. The particles adhered selectively with perchloroethylene and CFC-113. Propylene glycol monomethyl ether agent detailed information in Haz-Map database. © 2021 Eastman Chemical Company or its subsidiaries. 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. Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid, which is nearly odorless but possesses a faintly sweet taste.Its chemical formula is CH 3 CH(OH)CH 2 OH. ; 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. As can be seen from Table 3, weft shrinkage was within 2%, but what is to be noted is that there was no great shrinkage at all even when water was added at 50%. A solvent with little counter-contamination is good in the finishing of dry cleaning, and can clean even with a liquid containing a great deal of contamination, and the number of distillations may be economically reduced. It is sold by Dow Chemical under the name Dowanol PMA, by Shell Chemical under the name methyl proxitol acetate, and by Eastman under the name PM Acetate . A2, Designated state(s): Propylene glycol methyl ether (PGME or 1-methoxy-2-propanol) is an organic solvent with a wide variety of industrial and commercial uses. Shanghai King Chemicals Co., Ltd.

On the other hand, since the soy sauce was completely dissolved in water and PM, no dying or counter-contamination was exhibited. 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. These solvents typically have a higher boiling point, together with the favorable solvent properties of lower-molecular weight ethers and alcohols. (Ref. This is due to the good hydratability of PM. 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 â¦ 1.1.4 Physical properties (Ref. 2097173, Country of ref document: Counter-contamination is determined in consideration of the type of contamination (solute), the solvent and the kind of clothing, and therefore, the following test was carried out: as the water-soluble solute soy sauce (0.5 ml) and coffee (0.5 g) were used; as the dispersible solute carbon black (0.04 g) was used; as the oil-soluble solute waste oil after prolonged usage of gear oil (2 g) was used and, as the miscible solute, distillation residue of cleaning (0.04g) was employed. 1-Methoxy-2-propanol was produced in nearly 90% yield under much milder conditions. On the other hand, "handleability" is measured by easy drying of the article to be washed, long life, easy distillation and recovery of the solvent, suitability for machines with no corrosion of metals, easy workability and management with low odor, no remaining odor on the article to be washed, etc. Propylene glycol methyl ether (PGME or 1-methoxy-2-propanol) is an organic solvent with a wide variety of industrial and commercial uses.

Related Pages. 20400/1988), solvent for floor use (Japanese Unexamined Patent Publications Nos. May initiate the polymerization of isocyanates and epoxides. Propylene glycol ethers. Propylene glycol monomethyl ether (hereinafter referred to as PM) has been known in the art as a solvent for home use (Japanese Unexamined Patent Publication No. EP0479146B1 EP19910116518 EP91116518A EP0479146B1 EP 0479146 B1 EP0479146 B1 EP 0479146B1 EP 19910116518 EP19910116518 EP 19910116518 EP 91116518 A EP91116518 A EP 91116518A EP 0479146 B1 EP0479146 B1 EP 0479146B1 It did not adhere to the wool or polyester, which have hydrophobic surfaces. DPGME is used as a solvent for paints, lacquers, resins, dyes, oil/greases, cleaners and cellulose and as a heat-transfer agent. (5) There is no corrosion of cleaning machine, etc. The present inventor has previously investigated the dry cleaning capabilities of 81 kinds of solvents (Journal of the Japan Research Association for textile End-use 27, 8 (1986), 352 - 359), but there was no solvent which met all requirements. Get it here from the leading manufacturers. From the results as described above, PM exhibits low counter-contamination for all kinds of contamination and clothing, and therefore can be evaluated as an excellent solvent for dry cleaning. The Propylene Glycol Monomethyl Ether Propionate (PMP) report has recently added by MarketInsightsReports to get a stronger and effective business outlook. From Table 1, it can be seen that PM has both oil solubility and water solubility, and therefore is as effective on oil-soluble soils as the solvent of the prior art, and exhibits relatively better solubility for water-soluble soils, although inferior to water. It is preferable that the water content is not more than 25 %, since the shrinkage of a weft of a cotton remains by 5 %.
