The application belongs to the technical field of molecular biology, and particularly relates to metabolic markers for evaluating the prognosis of patients with hypertrophic cardiomyopathy and application thereof. The application determines that one or more of 3-hydroxyrilotene, asparagine-lysine, cyclohexylamine, arachidonic acid, aconitic acid, propionyl carnitine, ceramide, tryptophan, 3-hydroxysebacic acid, traumatic acid, phosphatidylcholine, alanine-proline, lysophosphatidylcholine, taurine and S-garlicin cysteine are related to the prognosis of hypertrophic cardiomyopathy, can evaluate the prognosis of patients with hypertrophic cardiomyopathy after undergoing muscle resection of interventricular septum, and shows accurate judgment on all-cause death or rehospitalization, cardiovascular events and postoperative new-onset arrhythmia. Finally, all the prognostic biomarkers are reproduced in an independent cohort, which is helpful for postoperative risk evaluation of patients with hypertrophic cardiomyopathy, has high specificity and high sensitivity.

The invention discloses oxidized paraffin and antirust wax and a preparation method thereof, and relates to the field of paraffin. The antirust wax comprises oxidized paraffin, an emulsifier, an antirust agent and water, and the emulsifier is at least one of sorbitan monooleate, lauryl sodium sulfate and fatty alcohol-polyoxyethylene ether; the antirust agent is at least one of cyclohexylamine stearate, alkenyl succinic acid and alpha-mercaptobenzothiazole; the oxidized paraffin is loaded with a Mn metal element through a carrier. The catalyst loaded with the active component Mn is added in the preparation process of the oxidized paraffin, the acid value and the soap value of the oxidized paraffin are effectively increased, the oxidized paraffin interacts with the specific emulsifier and the antirust agent, the emulsifier does not affect the anti-oxidation protection function of functional components, and meanwhile, the antirust agent and the oxidized paraffin cooperate with each other to achieve the anti-corrosion effect in a synergistic mode; and the antirust capability of metal in a humid and hot environment and an acid-base environment is improved, and the application prospect is expanded.

This invention discloses a cyclohexylaminosilane coupling agent production apparatus and its production process, belonging to the field of coupling agent production technology. The cyclohexylaminosilane coupling agent production apparatus of this invention includes a synthesis kettle, a centrifuge, and a distillation column. The inlet of the synthesis kettle is equipped with a metering tank, the outlet of the synthesis kettle is connected to the centrifuge, the outlet of the centrifuge is connected to a crude product storage tank, and the output end of the crude product storage tank is equipped with a distillation column. This invention solves the problem that existing reaction devices cannot achieve reflux. The cyclohexylaminosilane coupling agent production apparatus and its production process proposed in this invention are equipped with a continuously processing synthesis kettle, centrifuge, and distillation column, facilitating the synthesis, separation, and distillation of the cyclohexylaminosilane coupling agent. A stirring reflux assembly is installed in the synthesis kettle, and a drive motor drives a rotating shaft to rotate. The spiral blades follow the rotating shaft, pushing the liquid in the limiting cylinder upwards to form reflux.

The present application belongs to the technical field of rubber vulcanization accelerator production, and relates to a method for preparing vulcanization accelerator CBS by catalytic oxidation. A catalyst, MBT and distilled water are mixed in a reaction kettle and fully stirred, cyclohexylamine is added, and M-cyclohexylamine salt is generated by stirring and beating. Hydrogen peroxide solution is added dropwise, and the end point of the oxidation reaction is detected by using an indicator. The reaction kettle system is naturally cooled to room temperature, solid-liquid separation is performed, water washing is performed until neutral, the obtained wet product is placed in an oven for drying, and the finished product CBS is obtained after drying. The present application only uses hydrogen peroxide as an oxidizing agent, and the yield of the accelerator CBS is almost equivalent to the yield of CBS by using sodium hypochlorite as an oxidizing agent in the current industry (or the yield of CBS by using a mixed oxidation method). The present application has the potential for large-scale industrial production. The whole operation process is relatively simple, the conditions are mild, and the process belongs to an environment-friendly type, which is beneficial to large-scale industrialization.
