The objective of the following study was to identify the source of high concentrations of glycol diethers (diglyme, triglyme, and tetraglyme) in the Oder River. Altogether four sampling campaigns were conducted and over 50 surface samples collected. During the first two samplings of the Oder River in the Oderbruch region (km 626-690), glymes were detected at concentrations reaching 0.065mugL-1 (diglyme), 0.54mugL-1 (triglyme) and 1.7mugL-1 (tetraglyme). The subsequent sampling of the Oder River, from the area close to the source to the Poland-Germany border (about 500km) helped to identify the possible area of the dominating glyme entry into the river between km 310 and km 331. During that sampling, the maximum concentration of triglyme was 0.46mugL-1 and tetraglyme 2.2mugL-1; diglyme was not detected. The final sampling focused on the previously identified area of glyme entry, as well as on tributaries of the Oder River. Samples from Czarna Woda stream and Kaczawa River contained even higher concentrations of diglyme, triglyme, and tetraglyme, reaching 5.2mugL-1, 13mugL-1 and 81mugL-1, respectively. Finally, three water samples were analyzed from a wastewater treatment plant receiving influents from a Copper Smelter and Refinery; diglyme, triglyme, and tetraglyme were present at a maximum concentration of 1700mugL-1, 13,000mugL-1, and 190,000mugL-1, respectively. Further research helped to identify the source of glymes in the wastewater. The gas desulfurization process Solinox uses a mixture of glymes (Genosorb1900) as a physical absorption medium to remove sulfur dioxide from off-gases from the power plant. The wastewater generated from the process and from the maintenance of the equipment is initially directed to the wastewater treatment plant where it undergoes mechanical and chemical treatment processes before being discharged to the tributaries of the Oder River. Although monoglyme was also analyzed, it was not detected in any of the water samples.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.92420-89-8, Name is (2S,3S,4S,5R,6R)-2-(Methoxycarbonyl)-6-(2,2,2-trichloro-1-iminoethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate, molecular formula is C15H18Cl3NO10. In a Article，once mentioned of 92420-89-8, category: Tetrahydropyrans

A practical synthesis of beta-D-GlcA-(1?3)-beta-D-Gal-(1?3)-beta-D-Gal-(1?4)- beta-D-Xyl-(1?OMe) was achieved by coupling of methyl 2,3,4-tri-O-acetyl-alpha-D-glucopyranosyluronate trichloroacetimidate with a trisaccharide acceptor. The trisaccharide acceptor was obtained by condensation of 3-O-allyl-2,4,6-tri-O-benzoyl-beta-D-galactopyranosyl-(1?3)-2,4,6- tri-O-benzoyl-alpha-D-galactopyranosyl trichloroacetimidate with methyl 2,3-di-O-benzoyl-beta-D-xylopyranoside, followed by deallylation. The beta-(1?3)-linked disaccharide was prepared readily with p-methoxyphenyl 3-O-allyl-2,4,6-tri-O-benzoyl-beta-D-galactopyranoside as the key synthon. The alpha-(1?3)-linkage was formed in considerable amount with galactose mono- and disaccharide trichloroacetimidate donors with C-2 neighboring group participation.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 3301-94-8, Name is 6-Butyltetrahydro-2H-pyran-2-one, SDS of cas: 3301-94-8.

The present invention relates to an improved fragrance controlled release system that can be incorporated into anhydrous consumer and cosmetic products such as powder laundry detergents, underarm deodorant or antiperspirant sticks, soap bars, body deodorant powders, foot spray, hygiene sprays, feminine napkin sprays, undergarment sprays, and the like that provides a high intensity odor signal such as a high impact fragrance burst in response to moisture. A selected fragrance is encapsulated in a water-sensitive matrix material. The high impact fragrance burst in response to moisture is achieved by formulating the fragrance or fragrance ingredients that are encapsulated to provide improved fragrance release in response to moisture. The encapsulated fragrance is formulated by combining fragrance ingredients such that their interaction with water results in increasing their relative content in the headspace of the system proximate environment after the system has been exposed to moisture. Examples of suitable fragrance ingredients have ClogP<=4.0 and boiling point<=300 degrees C. The present invention also can provide multiple fragrance bursts in response to moisture. Multiple fragrance bursts can be achieved by formulating the moisture sensitive matrix material with materials having different dissolution rates. The invention further relates to anhydrous consumer and cosmetic product compositions comprising the improved fragrance controlled release system of the present invention.

135643-82-2, Name is Methyl 2-((tetrahydro-2H-pyran-2-yl)oxy)acetate, molecular formula is C8H14O4, belongs to tetrahydropyrans compound, is a common compound. In a patnet, once mentioned the new application about 135643-82-2, HPLC of Formula: C8H14O4

Syntheses of the unsubstituted steroidal [3,2-b]furan (3a), thiophene (3b) and [2,3-b]furan (24) are described. Lithiation of the THP ethers 18a and 18b followed by the reaction with methyl disulfide and deprotection gave the 5?-methylsulfide derivatives 19a and 19b. Oxidation of the sulfides and ethynylation provided the compounds 2a and 2b. Swern oxidation of the [2,3-b]furan 24 with DMSO/TFAA/diisopropylethylamine resulted in oxidation to the 17-ketone and introduction of a 5?-methylthio group to give 25. Ethynylation at C-17 followed by oxidation of the sulfide group provided the product 27. 5?-Methylsulfonyl[3,2-b]furanosteroid 2a bound to the rat ventral prostate androgen receptor. However, the corresponding thiophene 2b and the [2,3-b]furan 27 lacked affinity for the receptor.
