Abstract: Diphenyl trichloro-ethanes can be prepared by effecting reaction between a phenol or anisole (methoxybenzene) with chloral in a solvent medium comprising sulfuric acid and a liquid aliphatic chlorohydrocarbon containing from 1 to 2 carbon atoms.

Abstract: A waste receiver for canine toilet use has a handle and two spread-apart arms at the end of the handle. A plastic bag with an open top has two upper tubular edge portions which are slipped over the arms and support the bag in an open position. By means of the handle, the bag is placed below a pet to receive droppings therein. The upper inner edges of the bag incorporate closure means which are used to seal the bag closed after use. In one form, a mechanism on the handle closes the arms to at least partially seal a bag before its removal from the arms. In another form, spring arms meet at their tips to apply pressure and seal a bag as it is being removed from the arms.
