Abstract: Disclosed is a method for making dimethyl ether by reactive distillation. The method provides a reactive distillation tower with a top, a bottom, and rectification, reaction and stripping zones defined therein. The top of the reactive distillation tower is retained at 25° C. to 40° C. while the bottom of the reactive distillation tower is retained at 84.6° C. to 170° C. Each of the rectification, reaction and stripping zones includes several sieving trays. The reaction zone of the reactive distillation tower is filled with catalyst. The pressure in the reactive distillation tower is lower than 8.0 bars. Methanol is introduced into the reactive distillation tower so that the methanol travels from the reaction zone toward the bottom for contact with the catalyst to provide a top stream and a bottom stream. The top stream includes dimethyl ether. The bottom stream includes water and a remaining portion of the methanol. Finally, the dimethyl ether is collected in the top of the reactive distillation tower.

Abstract: The present invention discloses a method for solidifying and stabilizing waste acid including steps of condensing waste acid containing phosphoric acid to reduce the volume; mixing the condensed waste acid with waste acid containing fluoroboric acid to solidify and stabilize the mixed waste acid. The pH of the mixed acid is adjusted by adding barium hydroxide as a neutralizer. The efficiency of solidifying waste acid can be improved by partially granulating and by adding solidifying agent indirectly. The method of the present invention can prevent intensely exothermic reaction caused by adding solidifying agents. Furthermore, the method of the present invention is controlled in a temperature of 30 to 45° C. to improve the polymerization of the mixed waste acid so that the efficiency of solidification thereof can be also improved.

Abstract: Human neutrophil peptide (HNP) 1-3, used as diagnostic and therapeutic molecular probes, are found in clinical tissues of gastric cancer patients. In the analytical process according to the present disclosure, pairs of gastric cancer tissues are used to seek the putative biomarkers by proteomic strategy based on matrix assisted laser desorption ionization-imaging mass spectrometry (MALDI-IMS). Then, three differential biomarkers, including HNP-1, -2 and -3, are identified (P<0.001) and overexpressed in gastric cancer. At last, western blotting and immunohistochemistry are used to validate the protein expression in gastric cancer tissues. In conclusion, the use of the up-regulated proteins, HNP1-3, helps diagnosis and therapy in clinical for gastric cancer after validating the sensitivity and specificity.
