摘要： This invention relates to methods for racemization of dextro-rotatory ephedrine via enzymatic kinetic conversion, and is particularly useful for conversion of dextro- rotatory ephedrine (d- ephedrine) to racemic mixture of dextro-rotatory ephedrine (d-ephedrine) and levo-rotatory ephedrine (l-ephedrine) to recover the levo-rotatory ephedrine that exhibit potential bronchodilatory and anti-hypotensive activities. The process provides a suspension of Rhizopus Oryzae fungi pellets in diammonium phosphate buffer having pH in the range of pH 5 to 9 and effective sonication to extract specific enzymes for inversion of functional groups present on the chiral carbon atom of d-ephedrine molecule at low temperature which has advantages of working at lower temperature range (20 to 50 °C), lower energy consumption, lesser formation of by-products.

摘要： System and method for production of membrane having high strength, enhanced thermal stability and chemical resistance comprising of at least two furnace plates, at least one heating coils encased in ceramic disc housing, metal sheet and base. Perforated ceramic discs of the invention are mounted on a movable stand and equipped with heating mantle, insulation and is encased in a metallic cover. The pores present on ceramic disc not only helps in dissipation of gases emanating from heating of wet metal oxide gel diaphragms but also conducts the heat from heating coil to it. The pores in the ceramic disc plays dual role i.e. exit of trapped water and other organic matter as well as entry of heat towards the wet gel films for faster drying. On the other hand the perforated ceramic disc has a major role to play in preventing the deformation likely to occur during sintering of semidried metal oxide gel diaphragms by putting a vertical pressure and controlling its morphology as the heating progresses towards high temperature in controlled manner. By means of this setup the semidried gel diaphragms are calcined at high temperatures to get the desired flawless plain porous ceramic membranes and all operations are done smoothly.
