摘要:
Reversibly and irreversibly-linking amino-polysiloxanes, methods of making such amino-polysiloxanes, and systems and methods of using such amino-polysiloxanes for the containment and/or remediation of a release and/or spill of a crude oil, a petroleum product and/or a chemical is described. Gels and/or emulsions formed from the combination and/or contacting of such an amino-polysiloxane with these materials can be used to recover these oils or chemicals while allowing the amino-polysiloxane to be recovered and reused to clean up or contain additional materials. Such amino-polysiloxanes can be used as well for the selective uptake of one component of liquid mixtures when such mixtures contain more and less lipophilic components. Methods of making and using adhesive and sealants containing such amino-polysiloxanes are described. The adhesive and sealants can be used in a variety of applications to adhere and/or seal various materials including plastics, metals, glass, ceramics, paper, paper products, wood, and wood products.
摘要:
One aspect of the present invention relates to salts that are room-temperature ionic liquids (RTILs), methods of making them, and methods of using them in connection with temporary or permanent gas sequestration. Another aspect of the present invention relates to a class of solvents which can be transformed into RTILs by exposure to a gas, and methods of using them in connection with temporary or permanent gas sequestration.

摘要:
Low molecular weight gelators, methods of making such gelators, organogels comprising such gelators and systems and methods of using such gelators for the containment and/or remediation of a release and/or spill of a crude oil, a petroleum product and/or a chemical is described. In exemplary systems and methods, gels and/or emulsions formed from the combination and/or contact of such gelators and at least one of a crude oil, a petroleum product and a chemical from a release and/or spill into the environment can be used to recover these oils or chemicals while allowing the gelators to be recovered and reused to clean up or contain additional crude oil, petroleum products or chemicals.

摘要:
Gelators gel a variety of nonpolar and polar liquids. Moreover, gelation of various monomers with subsequent polymerization of the gelled monomers forms organic zeolites and membrane materials. An ionic gelator includes salts of compounds of the formula (I):�R.sup.1 R.sup.2 R.sup.3 X-R.sup.4 !.+-.Y.-+. (I)where R.sup.1, R.sup.2 and R.sup.3 are the same or different hydrogen or organic groups including alkyl groups, alkenyl groups, alkynyl groups, aryl groups, arylalkyl groups, alkoxy groups, aryloxy groups; X is a Group IIIA or Group VA element; R.sup.4 is a steroidal group, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an arylalkyl group, an alkoxy group or an aryloxy group; and Y is a Group IA or Group VIIA element or one-half of a Group IIA or VIA element, that is, a divalent counterion. The gelling agent composition may include a single isomer or mixtures of isomers of the formula (I). A non-ionic gelator also includes compounds of the formula:R.sup.1 R.sup.2 R.sup.3 X (II)where R.sup.1, R.sup.2, R.sup.3 and X are defined as above.
