Definitions
- ABSTRACT Defoamer compositions and method of defoaming aqueous systems such as latex or paper and pulp systems, for example, compositions being composed of certain fatty amides, inorganic particles (tale, for example), hydrocarbon liquid, an oil soluble polymer and a silicone oil.
- compositions such as inorganic particles, liquid hydrocarbons and silicone oils have been used in the preparation of defoamer compositions. Although these compositions have been useful in suppressing and controlling foam formation, they have the disadvantage in that the solid particles therein tend to settle on standing. Consequently, after standing for extended periods of time, it was necessary to agitate the compositions immediately prior to use.
- Defoamer compositions have been prepared by using certain amides, inorganic particles, a liquid hydrocarbon, an oil soluble polymer and a silicone oil.
- the compositions contain from about 1 to about 12 parts by weight of certain amides, from about 5 to about 25 parts by weight of inorganic particles, from about 70 to about 92 parts by weight of a liquid hydrocarbon, from about 0.5 to about 7.5 parts by weight of an oil soluble polymer and from to about 0.2 parts by weight of silicone oil. It has been found that the solid or particulate matter in such compositions tends to remain suspended on standing forsignificantly longer periods of time.
- Useful amides include those obtained by reaction of a polyamine containing at least one alkylene group having'from two to six carbon atoms and a fatty acid having from six to 18 carbon atoms.
- the amide obtained by'reaction of a polyamine and a fatty acid or mixture of fatty acids such as hexanoic, decanoic, lauric, palmitic, oleic and stearic acids, hydroxy acids such as ricinoleic acid or naphthenic acids such as are obtained as byproducts from the refining of petroleum. Natural mixtures of fatty acids such as, tall oil acids, tallow fatty acids and the like can be used.
- Suitable amines include ethylene diamine, butylene diamine, diethylene triamine, triethylene tetramine, hexamethylene diamine, decamethylene diamine, hydroxyethyl ethylene diamine, 1:3- diamino-Z-propanol or the like.
- One of the amides useful herein is prepared in the following manner. 95.7 parts by weight of bleached-hydrogenated tallow fatty acids is charged into a stainless steel reactor equipped with a condenser, water trap and agitator. The entire process including charging of reactants and cooling of the reaction product is carried out under a nitrogen atmosphere. The acids charge is heated to about 165 C. to about 175 C. and 10.1 parts by weight of ethylene diamine is added with agitation. After the diamine is added, the reaction mixture is heated to about 180 C. to about 185 C. The mixture is reacted at about 180 C. to about 185 C. until the acid value is less than 5 the alkalinity Scott-Volumeter than 0.6 percent by weight. The resulting reaction product of ethylene diamine and tallow fatty acid is then cooled to room temperature. If desired, the cooled mass can be ground to obtain the product in the form of a very fine powder.
- Inorganic particles such as talc or powdered calcium hydroxide can be used.
- a suitable talc is a fluffy talc (E V Micro Talc Charles B. Chrystal Co. Inc., N.Y., N.Y.) having a bulking value of 26 pounds per cubic foot or an average of 3.53 grams per cubic inch on the'Scott-Volumeter Test. This talc has an average particle size of 3.5 microns and 99.98 percent by weight of which passes through a 325 mesh screen. It is used in the manufacture of pressed powders and dusting powders.
- talc P-275 lntemational Talc Co., Inc., N.Y., NY.
- a platey talc' which has an average particle size of 1.4 microns and 99.99 percent by weight of which passes through a 325 mesh screen.
- This talc has a Hegman fineness of about 6 and'high oil absorption. It is used in housepaints, primers, lacquers and industrial finishes.
- a suitable powdered calcium hydroxide is a hydrate of lime containing about by weight of calcium hydroxide. Atypical sample of this material after jet milling gave the following 1 results in a screen test:
- the liquid hydrocarbon can be any liquid aliphatic, alicyclic, aromatic hydrocarbon or mixture thereof.
- the hydrocarbon should be liquid at room temperature and atmospheric pressure, have a viscosity of from about 30 to about 400 SUS (Saybolt Universal Seconds at 100 F.), a minimum boiling point of at least F. and an average from about six to 25 carbon atoms.
- Suitable hydrocarbons include benzene, hexane, heptane, octane, mineral seal oil, stoddard solvent, petroleum naphtha, toluene, xylene, paraffinic mineral oil, naphthenic mineral oil or thelike. If desired mixtures of two or more hydrocarbons can be used.
- oil soluble polymer is a copolymer of vinyl acetate and fumaric acid esterified with a tallow alcohol.
- oil soluble polymer available from Enjay Chemical Co. in the form of a mineral oil solution thereof under the trade name Paratone 440 which consists of about 25 parts by weight of said copolymer in 75 parts by weight of a liquid hydrocarbon.
- Paratone 440 which consists of about 25 parts by weight of said copolymer in 75 parts by weight of a liquid hydrocarbon.
- the silicone oil can be a polysiloxane oil such as an alkyl, aryl, alicyclic or aralkyl siloxane or polysiloxanehaving a viscosity of from about 10 to about 3,000 centistokes at 25 C.
- Preferred silicone oils include alkyl polysiloxanes having viscosities of from about 40 to about 1,000 centistokes at 25 C.
- alkyl polysiloxanes include dimethyl polysiloxane, diethyl polysiloxane, dipropyl polysiloxane, methyl ethyl polysiloxane, dioctyl polysiloxane, dihexyl polysiloxane, methyl propyl polysiloxane, dibutyl polysiloxane, didodecyl polysiloxane or the like having a viscosity of from about 10 to about 3,000 centistokes at 25 C.
- the defoamer composition is prepared by mixing together the liquid hydrocarbon and oil soluble polymer and stirring until uniform. The inorganic particles and amide are added next. The mixture is then heated to about C. and held for 15 minutes at about 160 C. After cooling to room temperature, the formulation is homogenized using a hand homogenizer (C. W. Logeman Co., Brooklyn, N.Y.). Finally, if desired, the silicone oil is added with stirring.
- a hand homogenizer C. W. Logeman Co., Brooklyn, N.Y.
- the defoamer composition was evaluated for settling in the following manner. Fresh, homogenized formulation was added to a standard capped 2oz. jar to an arbitrary height, that is, about 5 cm. After standing for four days, three layers were observed, i.e., a settlement at the bottom, a gelatinous suspension above the bottom layer and a relatively clear liquid layer at the top. The height of the settlement at the bottom was .recorded.
- the defoamers of this invention are especially adapted to defoam aqueous systems such as are found in the preparation of latex, glues, resinous materials, starches, paper, pulp and the like.
- the defoamer compositions are used in small amounts depending upon the system in which they are emloyed. In general, from about 0.01 percent to about 0.5 percent by weight of the defoamer based on the foam producing materials present in the aqueous system is satisfactory. Amounts in excess of about 0.5 percent by weight can be utilized to defoam the aqueous systems but generally such amounts are not practical due to the high cost of the defoamer.
