Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A method for deodorizing odoriferous materials characterized by containing one or more of mercaptans, hydrogen sulfide, ammonia or amines as a bad-smelling component, which comprises applying to said material an effective deodorizing amount of a deodorizing compound or a mixture of deodorizing compounds selected from the group consisting of (A) a compound having the formula ##STR3## and (B) a compound having the formula ##STR4## wherein M is hydrogen, sodium, potassium, ammonium, monoethanolamine, diethanolamine, triethanolamine, methylamine, dimethylamine, ethylamine, diethylamine, methylethylamine, propylamine, methylpropylamine or methylbutylamine, R 1 is alkyl having one to 20 carbon atoms or alkenyl having 2 to 20 carbon atoms, and R 2 is hydrogen, alkyl having one to 20 carbon atoms or alkenyl having two to 20 carbon atoms, sufficient to substantially reduce the content of said bad-smelling component of the odoriferous material.
Claim 2
Independent Claim
135 words
A method for deodorizing odoriferous materials characterized by containing one or more of mercaptans, hydrogen sulfide, ammonia or amines as a bad-smelling component, which comprises applying to said material an effective deodorizing amount of a deodorizing compound or a mixture of deodorizing compounds selected from the group consisting of (A) a compound having the formula ##STR3## and (B) a compound having the formula ##STR4## wherein M is hydrogen, sodium, potassium, ammonium, monoethanolamine, diethanolamine, triethanolamine, methylamine, dimethylamine, ethylamine, diethylamine, methylethylamine, propylamine, methylpropylamine or methylbutylamine, R 1 is alkyl having one to 20 carbon atoms or alkenyl having 2 to 20 carbon atoms, and R 2 is hydrogen, alkyl having one to 20 carbon atoms or alkenyl having two to 20 carbon atoms, sufficient to substantially reduce the content of said bad-smelling component of the odoriferous material.
Claim 3
Dependent Claim
63 words
The method according to claim 1, wherein said deodorizing compound is applied to the odoriferous material in the form of a solution or an emulsion in a liquid carrier selected from the group consisting of water, an alkanol having one to 3 carbon atoms, acetone and mixtures thereof, said solution or emulsion containing from 0.1 to 5 weight percent of said deodorizing compound.
Claim 4
Dependent Claim
42 words
The method according to claim 1, wherein said deodorizing compound is applied to the odoriferous material in the form of a powder or granules containing 0.1 to 5 weight percent of said deodorizing compound and the balance consists essentially of a filler.
Claim 5
Dependent Claim
22 words
The method of claim 1 wherein said compound is selected from the group consisting of beta-acetyl-acrylic acid, beta-methylbenzoyl-acrylic acid and beta-nonylbenzoyl-acrylic acid.
