The granular absorbent is ground and screened to a particle size between 4 mesh and about 100 mesh. In another aspect of the invention, an effective amount of a binder such as a clay, lignin or starch is added to the calcium sulfate to assist the calcium sulfate to pelletize and form granules. The granules are sized and dried. The granular absorbents are effective in absorbing oil or water and are easily disposed of. There is also disclosed processes for making the granular absorbents.Type: ApplicationFiled: January 4, 2001Publication date: May 31, 2001Applicant: ABSORBENT AND PROCESS FOR MAKING SAMEInventors: Richard Binion Steele, Donald Frederick Evans

Patent number: 5972049Abstract: Improvements in the disperse dyeing process for hydrophobic textiles by the use of novel dye carrier formulations are disclosed. The carrier composition for use in disperse dyeing of hydrophobic textile material preferably comprises an alkylphthalimide carrier component and a clay dispersing agent. Dye baths and methods of disperse dyeing of a hydrophobic textile material are also disclosed. The use of clay as a dispersing agent allows for the use of carrier compositions with reduced health and environmental hazards without adversely affecting dyeing characteristics.Type: GrantFiled: January 28, 1998Date of Patent: October 26, 1999Assignee: Sybron Chemicals Inc.Inventors: Calvin M. Wicker, Jr., Otto Bello, Ricky C. Phillips, Robert B. Login

Patent number: 5952095Abstract: Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer including an alkyl radical having at least 10 carbon atoms and having a dipole moment greater than the dipole moment of water, to sorb or intercalate the intercalant monomer between adjacent platelets of the layered material. Sufficient intercalant monomer is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 .ANG. (as measured after water removal to a maximum of 5% by weight water), up to about 100 .ANG. and preferably in the range of about 10-45 .ANG., so that the intercalate easily can be exfoliated into individual platelets. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix.Type: GrantFiled: December 6, 1996Date of Patent: September 14, 1999Assignee: AMCOL International CorporationInventors: Gary W. Beall, Fernando Serrano, Semeon Tsipursky, Steven J. Engman
