摘要:
Amino phenols of the general formula ##STR1## wherein R is a substantially saturated, hydrocarbon-based group of at least about 30 aliphatic carbon atoms, a, b and c are, for example, each 1, 2 or 3, and Ar is an aromatic moiety such as a benzene nucleus, naphthalene nucleus or linked benzene nuclei, are useful additives for fuels and lubricants. These amino phenols can be conveniently prepared by nitrating an appropriate hydroxy aromatic compound and reducing the nitro groups to amino groups. Typically such amino phenols are formed by nitration and reduction of alkyl phenols having an alkyl or alkenyl group of at least about 50 carbon atoms.

A process for making the foregoing partially dehydrated product is also disclosed. Emulsions comprising an organic phase, an aqueous phase, and an emulsifying amount of the foregoing partially dehydrated product are disclosed.
摘要:
A sand trap rake arranged particularly for use on a golf course and with fingers which penetrate the sand for plowing the sand. There is an adjustment relative to the plowing fingers which permits the fingers to be angulated so that they can be dragged through the sand with the tips of the fingers being in trailing position. The entire machine includes the plowing fingers arranged on one planar piece and being disposed in a plurality thereof in end-to-end relationship to each other and with dresser plates trailing the plowing fingers for smoothing the top of the sand.
