New compounds and a method for inhibiting the growth of fungus is disclosed which comprises contacting said fungus with a fungicidal amount of a phenyl glycine compound of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are independently hydrogen, lower alkyl, substituted lower alkyl, cycloalkyl, substituted cycloalkyl, alkenyl, phenyl, substituted phenyl, halogen, amino or hydroxy groups; R.sub.3 is a hydrogen, lower alkyl, substituted lower alkyl, cycloalkyl, benzoyl, halo or nitro substituted benzoyl, substituted cycloalkyl, methylcarbamoyl, cyclohexylcarbamoyl, phenylcarbamoyl, halophenylcarbamoyl, methylphenylcarbamoyl, methylthiocarbamoyl, phenyl, substituted phenyl, napthyl group or --SO.sub.2 R.sub.7 where R.sub.7 is a hydrogen, alkyl, substituted alkyl, phenyl, substituted phenyl or amino group; R.sub.4 and R.sub.5 are independently hydrogen, lower alkyl or substituted lower alkyl groups and R.sub.6 is a hydrogen, lower alkyl or substituted lower alkyl, alkenyl or substituted alkenyl group.

Method for inhibiting the growth of fungi with phenyl glycine compounds

The invention describes a method for inhibiting the growth of pests comprising applying thereto a pesticidal amount of a compound of the formula ##STR1## wherein R.sub.1, and R.sub.2 are independently hydrogen, substituted or unsubstituted lower alkyl, cycloalkyl, phenyl, or alkenyl, and halogen, amino or hydroxy groups, R.sub.3 and R.sub.4 are independently hydrogen or substituted or unsubstituted lower alkyl, R.sub.5 is hydrogen, substituted or unsubstituted lower alkyl, cycloalkyl or phenyl, and naphthyl groups; pesticidal compositions containing at least one of said compounds; and novel thiohydantoin compounds having pesticidal activity.

Pesticidal thiohydantoin compositions

Novel phenyl hydantoin compounds are disclosed of the structure: ##STR1## wherein R.sub.1 and R.sub.2 are independently hydrogen, amino, nitro, halogen, hydroxy, substituted and unsubstituted lower alkyl, cycloalkyl, phenyl and lower alkenyl; and R.sub.3 is substituted and unsubstituted lower alkyl, lower alkenyl and cycloalkyl; as well as pesticidal methods employing said novel compounds; and pesticidal compositions containing said novel compounds.

Insecticidal phenyl hydantoin compounds

N-phenyl carbamoyl glycinate compounds of the formula ##STR1## wherein R is lower alkyl, are disclosed as having anti-convulsant activity; and, methods are disclosed for producing anti-convulsant activity by administering pharmaceutical compositions containing at least one of said compounds.

Pharmaceutical N-phenyl carbamoyl glycinate compositions

A process for purifying 4,4'-dihydroxydiphenyl comprising contacting a solution of 4,4'-dihydroxydiphenyl alkali metal salt with activated carbon followed by removing the activated carbon from the solution and acidifying the solution with sufficient acid to convert essentially all of the 4,4'-dihydroxydiphenyl alkali metal salt to water insoluble 4,4'-dihydroxydiphenyl and 4,4'-dihydroxydiphenyl product containing less than 0.45 weight percent of 4-monohydroxydiphenyl impurity.

Process for the purification of 4,4' dihydroxydiphenyl

A process for the preparation of 4,4' dihydroxydiphenyl by acidifying an alkali metal salt of 4,4' dihydroxydiphenyl. The alkali metal salt of 4,4' dihydroxydiphenyl is prepared by fusion of an alkali metal hydroxide with alkali metal diphenyl 4,4' disulfonic acid. Because the reaction may be carried out in granular form, or in a reaction which is made highly fluid by using potassium hydroxide with potassium diphenyl 4,4' disulfonic acid, or by reacting the alkali metal 4,4' disulfonic acid in increments with the hydroxide, low molar ratios of hydroxide to alkali metal diphenyl 4'4, disulfonic acid may be used. When potassium diphenyl 4,4' disulfonic acid is used in accordance with the invention, it is prepared by reacting 4,4' diphenyl disulfonic acid with an inorganic neutral potassium salt.
