Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A stabilized composition comprising a compound of the formula: ##STR5## wherein Y is substituted or unsubstituted alkyl, unsubstituted or halo substituted alkenyl or alkynyl, and unsubstituted or substituted cycloalkyl, aralkyl or aryl and R and R 1 are hydrogen, halo or alkyl and an effective amount of an orthoester of the formula: C X(OR 2 )(OR 3 )(OR 4 ) wherein X is hydrogen, alkyl, OR 5 or aryl; R 2 , R 3 , R 4 and R 5 are the same or different radical selected from alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl.
Claim 2
Dependent Claim
94 words
A stabilized composition comprising a compound of the formula: ##STR5## wherein Y is substituted or unsubstituted alkyl, unsubstituted or halo substituted alkenyl or alkynyl, and unsubstituted or substituted cycloalkyl, aralkyl or aryl and R and R 1 are hydrogen, halo or alkyl and an effective amount of an orthoester of the formula: C X(OR 2 )(OR 3 )(OR 4 ) wherein X is hydrogen, alkyl, OR 5 or aryl; R 2 , R 3 , R 4 and R 5 are the same or different radical selected from alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl.
Claim 3
Dependent Claim
71 words
The composition of claim 1 which comprises from 0.1 to 99.9 parts of one or more compounds of the ##STR6## wherein R, R 1 and Y are as defined in claim 1 and from 0.1 to 99.9 parts of an orthoester of the formula: C X(OR.sup.2)(OR.sup.3)(OR.sup.4) wherein x, R 2 , R 3 and R 4 are as defined in claim 1 and from 0 to 99.8% of an organic solvent.
Claim 4
Dependent Claim
32 words
The composition of claim 2 which comprises from 1 to 50 parts of the isothiazolone; from 1 to 25 parts of the orthoester and from 25 to 98 parts of a solvent.
Claim 5
Dependent Claim
32 words
The composition of claim 3 which comprises from 1 to 25 parts of the isothiazolone, from 1 to 10 parts of the orthoester and from 30 to 98 parts of a solvent.
Claim 6
Dependent Claim
50 words
The composition of claim 4 wherein Y is C 1 -C 18 alkyl or C 3 -C 12 cycloalkyl; R is hydrogen or halo and R 1 is hydrogen or halo and R 2 , R 3 , R 4 are lower alkyl, and X is hydrogen, alkyl, or aryl.
Claim 7
Dependent Claim
19 words
The composition of claim 5 which comprises 14 parts of an isothiazolone selected from 5-chloro-2-methyl-3-isothiazolone, 2-methyl-3-isothiazolone, 2-octyl-3-isothiazolone, or 4,5-dichloro-2-octyl-3isothiazolone.
Claim 8
Dependent Claim
19 words
The composition of claim 5 which comprises 1.5 parts of an isothiazolone selected from 5-chloro-2-methyl-3-isothiazolone, 2-methyl-3-isothiazolone, 2-octyl-3-isothiazolone, or 4,5-dichloro-2-octyl-3isothiazolone.
Claim 9
Dependent Claim
22 words
The composition of claim 6 which comprises an orthoester selected from trimethyl orthoformate, triethyl orthoformate, triethyl orthoacetate, trimethyl orthovalerate or trimethyl orthobenzoate.
Claim 10
Independent Claim
119 words
A method for stabilizing a compound of the formula ##STR7## wherein Y is substituted or unsubstituted alkyl, unsubstituted or halo substituted alkenyl, and unsubstituted or substituted cycloalkyl, aralkyl or aryl and R and R 1 are hydrogen, halo or alkyl, useful for inhibiting the growth of bacteria, fungi, or algae in a locus subject to contamination by bacteria, fungi, or algae, comprising using in association with said compound an effective stabilizing amount of an orthoester of the formula: CS(OR 2 )(OR 3 )(OR 4 ) wherein X is hydrogen, alkyl, OR 5 or aryl, R 2 , R 3 , R 4 and R 5 are the same or different radical selected from alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl.
Claim 11
Independent Claim
119 words
A method for stabilizing a compound of the formula ##STR7## wherein Y is substituted or unsubstituted alkyl, unsubstituted or halo substituted alkenyl, and unsubstituted or substituted cycloalkyl, aralkyl or aryl and R and R 1 are hydrogen, halo or alkyl, useful for inhibiting the growth of bacteria, fungi, or algae in a locus subject to contamination by bacteria, fungi, or algae, comprising using in association with said compound an effective stabilizing amount of an orthoester of the formula: CS(OR 2 )(OR 3 )(OR 4 ) wherein X is hydrogen, alkyl, OR 5 or aryl, R 2 , R 3 , R 4 and R 5 are the same or different radical selected from alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl.
Claim 12
Dependent Claim
21 words
