Abstract
Abstract The invention discloses methods of making oil coagulant compositions, the oil coagulants made thereby and processes for using the coagulants to coagulate oil that has been spilled on water. The coagulant comprises a glyceride, such as, for example, the drying oil linseed oil, a polymer, such as, for example, poly(isobutyl methacrylate), and a solvent, such as, for example, 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate. The coagulant of the present invention coagulates oil independent of both agitation and temperature, and may be used in both salt and fresh water. After the coagulant has coagulated the spilled oil, the coagulated oil may be readily mechanically removed from the water such that at least 99.9% of the oil is removed from the water and only a faint trace of oil remains in the water.

Claim 5
Dependent Claim
30 words
A composition comprising a synthetic reaction product of about 74.6% linseed oil and about 25.4% poly (isobutyl methacrylate) which is further mixed with about 50% 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate.
Claim 6
Dependent Claim
30 words
A composition comprising a synthetic reaction product of about 74.6% linseed oil and about 25.4% poly (isobutyl methacrylate) which is further mixed with about 50% 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate.
Claim 7
Independent Claim
76 words
A method of using a composition to coagulate oil that has been spilled on water comprising the steps of: (a) applying a composition manufactured from linseed oil, poly(iso butyl methacrylate), and 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate to oil that has been spilled on water such that the percentage of said composition to said spilled oil ranges from 5-15%; and (b) allowing said composition and spilled oil to admix such that said composition coagulates said spilled oil.
Claim 8
Independent Claim
76 words
A method of using a composition to coagulate oil that has been spilled on water comprising the steps of: (a) applying a composition manufactured from linseed oil, poly(iso butyl methacrylate), and 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate to oil that has been spilled on water such that the percentage of said composition to said spilled oil ranges from 5-15%; and (b) allowing said composition and spilled oil to admix such that said composition coagulates said spilled oil.
Claim 9
Dependent Claim
15 words
The method of claim 4 wherein said coagulated oil is mechanically removed from the water.
Claim 10
Independent Claim
81 words
A method of using a composition to coagulate oil that has been spilled on water comprising: (a) applying a composition that has been manufactured from a glyceride, a polymer and a solvent to oil that has been spilled on water such that the percentage of said composition to said spilled oil ranges from about 5 to 15%; and (b) allowing said composition and spilled oil to admix such that said composition coagulates said spilled oil, wherein the polymer is poly(isobutyl methacrylate).
Claim 11
Independent Claim
81 words
A method of using a composition to coagulate oil that has been spilled on water comprising: (a) applying a composition that has been manufactured from a glyceride, a polymer and a solvent to oil that has been spilled on water such that the percentage of said composition to said spilled oil ranges from about 5 to 15%; and (b) allowing said composition and spilled oil to admix such that said composition coagulates said spilled oil, wherein the polymer is poly(isobutyl methacrylate).
