Abstract: A cationic cyanuric chloride derivative tanning agent and a preparation method thereof are disclosed. The method includes: mixing 9.22-36.88 parts of cyanuric chloride, 21.35-100.31 parts of a solvent, and 7.12-33.44 parts of deionized water, all by mass, in an ice-water bath to obtain a mixture A; at a temperature of 0-5° C., adding 2.98-20.44 parts of a tertiary ammonia compound to the mixture A, and subjecting the resulting mixture to a reaction for 4-6 hours, during which its pH value is adjusted with an acid-binding agent solution to 6.0-7.0, to obtain a mixture B; filtering the mixture B, washing the filter cake, and vacuum drying for 4-6 h to obtain a solid C, and grinding to obtain the cationic cyanuric chloride derivative tanning agent.

Abstract: A method for detecting adrenocorticotropic hormone comprising: bringing a liquid sample containing adrenocorticotropic hormone into contact with gelled casein to adsorb adrenocorticotropic hormone to the gelled casein; and detecting the adrenocorticotropic hormone adsorbed to the gelled casein is disclosed. An adsorbent of adrenocorticotropic hormone comprising gelled casein is also disclosed.
Abstract: Disclosed is a collagen powder and/or a collagen derivative powder, which are obtained by dispersing in a hydrophilic organic solvent a crude collagen precipitate which comprises 12 to 50% by mass of a collagen precipitate and/or a collagen derivative precipitate having an average particle size of 1 to 1,000 ?m, recovering solids and then drying the solids. By dispersing the crude collagen precipitate in the hydrophilic organic solvent, the resulting precipitates can be dehydrated, so that drying of the thus obtained solids can be done by air-drying. In addition, the resulting collagen powder and/or collagen derivative powder exhibit excellent solubility due to an increased specific surface area and also have excellent ease of handling with the average particle size being 8 to 1,000 ?m.
Abstract: The present invention provides an improved method of producing a stable acid denatured soy/urea adhesive having improved wet and dry strengths, with more efficient production and lower production costs. The method comprises combining urea with soy flour that has been acid treated until denatured and substantially free from urease activity. The soy flour is preferably lowered to a pH of 2.0 to 4.0 for at least 1 minute. Optionally, the method may also include adding a crosslinking agent, diluent or both to the soy flour/urea adhesive and/or adding an emulsified or dispersed polymer. Adhesives and dispersions prepared according to the methods of this invention offer increased stability and strength properties.
Abstract: A first variant of an adhesive composition for making a lignocellulosic composite includes soy protein and/or lignin; at least one substantially formaldehyde-free curing agent that includes at least one amine, amide, imine, imide, or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the soy protein; and at least one compound selected from a boron compound, a group IA oxide or hydroxide, or a group IIA oxide or hydroxide. A second variant of an adhesive composition includes a first component selected from soy protein and/or lignin; and at least one substantially formaldehyde-free curing agent selected from a reaction product of epichlorohydrin with ethylenediamine, a reaction product of epichlorohydrin with bis-hexamethylenetriamine, or a reaction product of epichlorohydrin with hexamethylenediamine.
