A method of making an alkylaminoarylcarbonyl compound having Formula I: ##STR1## wherein R is an alkyl group;A is an aryl (including heteroaryl) ring;each R' is independently an alkyl group which may form a ring with Z or Z';p is 0, 1, 2, or 3;each Z, Z', and Y is independently hydrogen or a substituent; andn is 0, 1, or 2;comprising:(a) blocking the carbonyl function of an aminoarylcarbonyl compound via condensation with an active methylene compound(b) alkylating this blocked amniocarbonyl compound via reductive alkylation with an alkyl or aryl (including heteroaryl) carbonyl compound, and(c) deblocking of the blocked alkylaminoarylcarbonyl compound via base hydrolysis to regenerate the carbonyl function and give the desired alkylaminocarbonyl compound.
摘要:
A photographic element having improved granularity contains a dye-forming coupler containing a carbamic acid precursor capable of being converted into a carbamic acid group during processing, and wherein after processing the carbamic acid group decomposes, leaving the dye substantially non-diffusable.
摘要:
Disclosed is a process comprising reacting a primary alcohol sulfone with a reducing agent and a halogenating agent in the presence of an amide compound present in an amount of less than 1 part amide per part of primary alcohol sulfone to form a vinylsulfone.
摘要:
A cleaning liquid dispensing system for use in a mobile hard floor surface cleaner includes fluid conduit and fluid communication with a supply of cleaning liquid, a pump, and a flow restriction member. The pump is adapted to drive a flow of the cleaning liquid through the conduit. The flow restriction member generates a pressure drop in the conduit, thereby restricting the flow of the cleaning liquid therethrough.
摘要:
A method of cleaning a hard floor surface with a surface maintenance vehicle including the steps of generating a foam-like aerated cleaning liquid, selectively conveying the foam-like aerated cleaning liquid to the hard floor surface and a scrubbing medium operatively coupled to the surface maintenance vehicle, scrubbing the hard floor surface with said rotating scrubbing medium and said foam-like aerated cleaning liquid so as to loosen soil from the hard floor surface leaving behind a soiled solution of cleaning liquid and soil, and removing at least a portion of the soiled solution from the hard floor surface through a fluid recovery device. Additional aspects of the present invention include devices for performing the cleaning method.
