    摘要: Provided is a method of preparing and recovering 2-methyl-5-iodobenzoic acid. The method utilizes o-methylbenzoic acid as raw material, iodinating via iodine/potassium persulfate in a mixed acid solvent to obtain a mixture of 2-methyl-5-iodobenzoic acid, 2-methyl-3-iodobenzoic acid, and 2-methyl-3, 5-diiodobenzoic acid; refining to obtain 2-methyl-5-iodobenzoic acid and recoverable mother liquor, the recoverable mother liquor being a mixture of 2-methyl-5-iodobenzoic acid, 2-methyl-3-iodobenzoic acid, and 2-methyl-3, 5-diiodobenzoic acid; conducting catalytic hydrogenation and deiodination to recover o-methylbenzoic acid and iodide ions; and oxidating the iodide ions to recover iodine. The whole process is recycled. The preparation and recovery method has cheap and easily available raw materials, and is easy of operation, has low requirements for equipment, and is suitable for large-scale industrial production.

    摘要: The present invention discloses 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt in different crystal forms and the preparation methods thereof, and belongs to the field of pharmaceutical chemistry. Said different crystal forms of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt include: amorphous 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt, crystal form A of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt, and crystal form B of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt. The different crystal forms of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt obtained according to the present invention have better stability and water-solubility than the mixed forms of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt, thus is advantageous for pharmaceutical use. Moreover, the different crystal forms of 5-bromo-2-(±-hydroxypentyl)benzoic acid sodium salt possess much better therapeutic effect than 5-bromo-2-(±-hydroxypentyl)benzoic acid potassium salt.

    摘要: Organozinc salts and mixtures thereof, organozinc salt coated particles, methods of preparing organozinc salts and organozinc salt coated particles, and various applications of such coated particles, including applications in rubber, other polymeric materials, and pesticides and/or fungicides are disclosed. As compared to rubber formulations without organozinc salt, formulations with organozinc salts including the present coated particles may have lower Mooney viscosity and lower minimum torque, improved dispersability, a higher modulus at 100% and/or at 300% elongation, a higher tensile strength, better aging resistance, better abrasion resistance, and/or lower heat buildup. Thus, products containing the present coated particles may enjoy similar or better properties than comparative products that include a conventional filler and/or organozinc salts per se, and the present coated particles may result in cost savings for the corresponding product formulations. The need for a silane coupling agent may also be reduced or eliminated.
