摘要： The invention relates to a method for obtaining cellulose by separating lignin from a biomass comprising lignocellulose in the form of plants or plant parts, wherein the biomass comprising lignocellulose is solubilized in a boiler in an alkaline medium comprising alkanol amine, and dissolved lignin is separated from the resulting raw cellulose. Said method is characterized in that the biomass comprising lignocellulose is not from a wood source, and is solubilized at a temperature of less than approximately 170° C. in a solubilizing agent based on alkanol amine and water, wherein the weight ratio of alkanol amine to water is set to 80:20 to 20:80, and raw cellulose thus produced is separated from the waste lye using a typical method. Said method is particularly advantageous for obtaining cellulose from annual plants, particularly wheat straw. The method is advantageously improved in that the solubilization takes place in the presence of a catalyst, particularly of anthrachinon. An advantageous bleaching process may be performed subsequently. Said method is characterized by great economic efficiency, particularly due to the high reclamation rates of the alkanol amine used, and leads to lower environmental impact in wastewater, and to reduced disposal costs. The design of the method leads to a greater yield of cellulose and largely prevents degradation of alkanol amine, particularly monoethanol amine (MEA).

摘要： The invention relates to a non-aqueous dispersion of organic polymer particles in a reactive diluent. Said non-aqueous dispersion can be obtained in that at least one monomer is polymerized in the reactive diluent, forming the organic polymer particles, wherein the reactive diluent does not participate in said polymerization due to the orthogonal reactivity thereof relative to the monomers, but comprises a functionality allowing later targeted polymerization. Depending on the organic polymer particles or reactive diluents used, the non-aqueous dispersion can be used in multifaceted applications having a wide range of application profiles. In order to produce said non-aqueous dispersion, polymerization of at least one monomer in a stirred tank reactor in the presence of a reactive diluent is particularly suitable, wherein the conversion is performed at a stirring speed of at least 2 m/s, wherein the ratio of the stirrer diameter to the vessel diameter is set to 0.3-0.80 and the distance from the stirrer to the vessel floor is set to 0.25 to 0.5 times the stirrer diameter. The invention provides multifaceted advantageous applications, particularly as an impact strength modifier, particularly in films, and as an adhesive, as casting resin, or as paint. A particularly advantageous application is producing a molded part or a semi-finished polymer product.
