Monoethers of alkylene glycols

Monoethers of alkylene glycols. McKinley, Suzanne V.; Rakshys, Joseph W., Jr. (Dow Chemical Co., USA). U.S. US 4011268 8 Mar 1977, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07C041-02. NCL: 260613000D. APPLICATION: US 73-390453 22 Aug 1973. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) The reactions of alcs. with propylene oxide (I) [75-56-9] to form glycol monoethers were catalyzed by insol. polymers contg. pendant phosphonium groups. Because of their insoly., the catalysts were easily removed from the reaction mixt. for reuse. 5510-99-6 and 108-95-2 are also in the experiment. Thus, 1 mole ethanol [64-17-5] was treated with 1 mole I 3.5 h at 100.degree. in the presence of 0.004 mole p-bromostyrene-divinylbenzene-styrene copolymer (II) [39311-03-0] contg. pendant phosphonium groups. Appreciable catalytic activity was retained after the catalyst was used for several cycles. The catalyst was prepd. by replacing the Br in II with Li, converting the Li to -(CH2)3OH by treatment with trimethylene oxide, converting the alc. to the iodide, reacting with Et3P followed by NaOAc and then EtOH-H2O. .

(English). (World Intellectual Property Organization). CODEN: PIXXD2. CLASS: ICM: C10L001-00. ICS: C10M171-00; C10L001-18. APPLICATION: WO 1996-US4666 2 Apr 1996. PRIORITY: US 1995-421325 13 Apr 1995. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Fluorescein and thymophthalein-type colorless markers for petroleum products are detected by adding a developing agent such as a quaternary alkyl ammonium base in a solvent (e.g., methanol, ethanol, propanol, arom. alcs., glycols, and glycol ether). The sample may be treated with an acid to remove the color and allow reuse of the sample. The method is suitable for diesel fuels, gasoline, and home heating oils. .
