Propoxy

After carrying out the reaction to the appropriate acid number, the water-reducible polyester is dissolved in an ether-alcohol such as l-propoxy-2-propanol [1569-01 -3] secondary alcohol should be used because primary alcohols lead to more rapid transesterification than... 

Most of the pharmacologically active indazole derivatives are useful as antiinflammatory drugs, e.g. bendazac or [(1-benzyl-l J/-indazol-3-yl)oxy]acetic acid (LDso in mice and rats of 355 and 388mgkg i.p., respectively) and benzydamine or l-benzyl-3-[3-(dimethyl-amino)propoxy]-l//-indazole (LDso in mice and rats of 110 and lOOmgkg" i.p., respectively). The last cited compound also has analgesic and antipyretic properties (B-76MI40404).

The mixture is stirred at room temperature for 7 hours, and then extracted with two 50 milliliter portions of benzene. The extract is washed with water, dried over anhydrous magnesium sulfate and the benzene is distilled off to give 8.5 grams of oily 1-(2,3-epoxy-propoxy)-2-(2-methoxyethoxy)benzene showing no ° = 1.5257. This compound has the methoxyethoxy group in place of the 2-tetrahydrofurfuryloxy group in Bufetrol.

A mixture of 1.63 g of 5-hydroxy-3,4-dihydrocarbostyril, 2.5 g of epibromohydrin and 2 drops of piperidine was heated at a temperature of 95°C to 100°C for a period of 4 hours with stirring. The reaction mixture was then concentrated to dryness under reduced pressure and the residue was recrystallized from acetone to obtain 1.2 g of 5-(2,3-epoxy)propoxy-3,4-dihy-drocarbostyril as a colorless powder having a melting point of 172°C to 173°C,...

Photodegradation of polyethylene waste can be markedly accelerated via its grafting with acrylamide [98], In contrast, photostabilization of polyethylene and polypropylene can be achieved as a result of the grafting of 2-hydroxy-4-(3-methacryloxy-2-hydroxy-propoxy) benzophenone using gamma radiation [ 147], In this case, the grafted compound acting as a U V stabilizer is chemically bound to the backbone chain of the polymer and its evaporation from the surface can be avoided.
