Abstract: A manufacturing method of separating and purifying neoagarooligosaccharides having degrees of polymerization of 2-22 includes the steps of adding crude enzyme solutions with agarases produced by Pseudomonas vesicularis MA103 and Aeromonas salmonicida MAEF108, respectively, into an agar polysaccharide extract solution, and obtaining a neoagarooligosaccharides solution after a hydrolysis on the algal polysaccharide (such as agar) is performed; performing a separation to the neoagarooligosaccharides solution by a ultrafiltration (UF) system to obtain a neoagarooligosaccharide eluent; performing a separation to the neoagarooligosaccharide eluent by a semi-preparative high-performance liquid chromatography system equipped with a molecule size exclusion chromatography function to obtain the neoagarooligosaccharides having the degrees of polymerization from 2 to 22; and using a fraction collector to collect the neoagarooligosaccharides, and obtaining purified single neoagarooligosaccharide products with different mo

Abstract: A system for determining a list of potential lots for consolidation is presented. The system includes a module having a database and an input for receiving an event occurrence. The database may include a set of consolidation rules. The module, upon receiving the event occurrence, retrieves the consolidation rules and initiates a consolidation analysis to determine the list of potential lots for consolidation based on the consolidation rules.

Abstract: A composition for treatment of a subterranean formation, which may be used for water control, is comprised of at least one of 1) a premix of an oleochemical polyol, at least one of polyisocyanate, polycyanate and polyisothiocyanate, and a blocking agent to temporarily block all or a portion of free reactive groups of said at least one of polyisocyanate, polycyanate and polyisothiocyanate. Alternatively, or in addition, the composition may be comprised of a solvent and 2) a polyurethane prepolymer formed by reacting an oleochemical polyol and at least one of polyisocyanate, polycyanate and polyisothiocyanate. A blocking agent may also be used with the polyurethane prepolymer. The composition may be used in a method of treating a subterranean formation penetrated by a wellbore by introducing the composition into the formation through the wellbore.

Abstract: A particle embedded with chemical substances, especially with physiological activity substances, is disclosed. The particle has (a) the embedded substances, embedded in base materials and ranged from about 0.1 to 70% by weight based on the total weight of the particle; and (b) the base material, selected from hydrogenated plant oil, hydrogenated animal oil, C8-C64 saturated fatty acid or the derivatives thereof, and ranged from about 30 to 99.9% by weight based on the total weight of the particle. Also, the present invention discloses a method for producing the particle.

Abstract: A coating composition containing a polyisocyanate compound having an isocyanate functionality of greater than 1, a polyol compound having an average hydroxyl functionality of greater than 1, wherein the relative amounts of polyisocyanate compound and polyol compound are in an amount effective to provide from 0.5 to 1.5 equivalents of isocyanate groups per equivalent of hydroxyl groups, from 0.0002 to 5 parts by weight of an organometallic curing catalyst selected from organobismuth, organozirconium or organoaluminum curing catalysts per 100 parts by weight of the polyisocyanate compound and from 0.0001 to 2.5 parts by weight of a moisture scavenger per 100 parts by weight of the polyisocyanate compound exhibits improved resistance to surface imperfections due to the phenomenon of “solvent popping”.

Abstract: Scavenging moisture from a polyisocyanate useful for preparing thermosetting polyurethane coatings therefrom is accomplished by admixing with the polyisocyanate a t-butylated hydroxytoluene and an alkyl ester of toluenesulfonic acid in which the alkyl ester comprises at least 90% para ester, thereby improving the shelf life of the polyisocyanate.

Abstract: Organic holographic recording media comprise organic photosensitive compounds such as .alpha.-diketones, quinones and nitro compounds in sucrose benzoate as host.
