Acetylation of residual primary and secondary alkyl amine groups in polymeric colorants, when said colorants are in the form of a crude preparation reaction mixture, is disclosed. The acetylation improves the colorants' water solubility.

Acetylation of crude reaction products containing polymeric colorants

Dihydrochalcones of the formula ##STR1## are disclosed wherein X is H or OH and R is a lower alkyl. These materials are useful as sweeteners for edibles. A process for preparing these compounds using a novel intermediate is disclosed as are acid and base neutralization products of the subject dihydrochalcones.

Flavonone precursors for alpha amino acid dihydrochalcones

Comestibles sweetened with alpha amino acid dihydrochalcones

Dihydrochalcones of the formula ##STR1## are disclosed wherein X is H or OH and R is lower alkyl. These materials are useful as sweeteners for edibles. A process for preparing these compounds using a novel intermediate is disclosed as are acid and base neutralization products of the subject dihydrochalcones.

Alpha amino acid dihydrochalcones

Dihydrochalcones of the formula ##STR1## are disclosed wherein M.sup.+ is a cation, X is H or OH, and R is a lower alkyl. These materials are useful as sweeteners for edibles. They may be prepared by electrophilic addition of the 3-sulfo-5,6-dihydroxyhexyl group to the corresponding flavanones, using epoxysultone, and thereafter converting to the dihydrochalcone.

4-(Dihydroxyhexoxy)dihydrochalcone sweeteners

Dihydrochalcones of the formula ##STR1## derivatizing group, Y is a polar group, X is hydrogen or hydroxyl and R is a lower alkyl, their preparation and their use as non-sugar sweeteners are disclosed.

Sweetener derivatives

Complexes of boron trihydride with solid particulate insoluble cross-linked thiohydrocarbon polymers are used in organic reduction reactions.

Reduction with polymeric reagent

Flavanones represented by the formula ##STR1## wherein R is a lower alkyl of from one to three carbon atoms inclusive, n is an integer of from one to three inclusive and M is hydrogen or a physiologically acceptable metal cation, are disclosed. These materials are themselves useful as dietetic sweeteners as well as being direct intermediates for the preparation of useful dihydrochalcone sweeteners.

Sulfoalkylated flavanone sweeteners

Polystyrene is halomethylated by contact with a solution of halomethoxybutane in a reaction medium (preferably halohydrocarbon) in the presence of a transition metal halide catalyst at a temperature of from about 5.degree. C to about 100.degree. C.

Halomethylation of polystyrene

A group of novel dihydrochalcone compounds represented by the formula ##SPC1## Wherein M is hydrogen or a pharmacologically acceptable cation and R is a lower saturated alkyl of from 1 to 4 carbon atoms, and their use as sweetening agents in food products are disclosed.

Ionic dihydrochalcone sweeteners and food product containing the same

Dihydrochalcones of the formula ##SPC1## Wherein D is a derivatizing group, Y is a polar group, X is hydrogen or hydroxyl and R is a lower alkyl, their preparation and their use as non-sugar sweeteners are disclosed.

A group of novel dihydrochalcone compounds represented by the formula ##SPC1## Wherein R is a lower alkyl or from one to three carbon atoms inclusive, n is an integer of from one to three inclusive and M is a physiologically acceptable metal cation, are disclosed. These materials are useful as dietetic sweeteners.

Ionic sweetener

The use of 3-amino-4-n-propoxybenzyl alcohol as a nonnutritive sweetener for foods, beverages and the like is disclosed.
