    摘要: A novel method for the preparation of aryl trifluoromethyl ethers which comprises reacting a phenol, a perhalomethane, and an antimony pentahalide. For example, 4-nitrophenol may be reacted with an excess over stoichiometry of both carbon tetrachloride and antimony trifluoride with a catalytic amount of antimony pentachloride to form 4-nitrophenyl trifluoromethyl ether.

    摘要: This invention relates to digestively hydrolyzable low calorie edible oil substitutes. These compounds have the organoleptic properties of normal triglycerides fats, but are lower in available calories. Specifically, the invention is directed to a composition of matter. The compositions are in one embodiment amides of dimer acids or trimer acids made from glycinates. The compounds are in part directed to amides based on the amino acid esters of the amino acid glycine. The utility of these compounds is in a low caloric edible oil.
