O-propyltoluen

Ipomoea batatas has long been used in folk medicine for the treatment of hyperglycemia or as a food additive for the prevention of type 2 diabetes. However, neither the plant extract nor its active components have been evaluated systematically. In this work four crude extracts, including n-hexane- (IBH), 95% MeOH- (IBM), n-BuOH- (IBB), and H2O-soluble (IBW) fractions, were prepared by

FIELD OF THE INVENTION [0002] This application is in the field of synthetic organic chemistry and is specifically an improved process for the synthesis of versatile intermediates, α-acyloxyacetaldehydes and their acetals, and their application to the synthesis of certain biologically active For example, n-octane is converted to ethylbenzene and predominantly o-xylene while n-decane gives primarily o-propyltoluene as well as o-diethylbenzene and n-butylbenzene. Studies of the factors determining selectivity and the mechanism and scope of these reactions and will be discussed. Abstract: This Landolt-Börnstein volume III/47 is a supplement to the volumes III/38 A/B "Optical Constants" and provides refractive index data published in the years 1995-2006. ----- EPA-600/2-75-076 November 1975 DEVELOPMENT OF ANALYTICAL TECHNIQUES FOR MEASURING AMBIENT ATMOSPHERIC CARCINOGENIC VAPORS by Edo D.
