- Erythromycin lactobionate 500 mg Dexamethasone Na phosphate 100 mg Glycerin 2.5 mL Sterile water for injection ad 100 mL M. ft. opthalmic solution a. what is the percentage strength of erythromycin lactobionate in the prescription? b. If glycerin has a specific gravity of 1.25, what is its concentration (in w/v) in the prescription?Gentiobiose has the molecular formula C12H22O11 and has been isolated from gentian root and by hydrolysis of amygdalin. Gentiobiose exists in two different forms, one melting at 86°C and the other at 190°C. The lower melting form is dextrorotatory ([α] 16°), the higher melting one is levorotatory ([α] -6°). The rotation of an aqueous solution of either form, however, gradually changes until a final value of [α] 9.6° is observed. Hydrolysis of gentiobiose is efficiently catalyzed by emulsin and produces two moles of D-glucose per mole of gentiobiose. Gentiobiose forms an octamethylether, which on hydrolysis in dilute acid yields 2,3,4,6-tetra-O-methyl-D-glucose and 2,3,4-tri-O-methyl-D-glucose. What is the structure of gentiobiose? EXPLAIN IN DETAIL.The task I have to do is to investigate the purification of Lactic Acid by means of Extraction with solvents and I found this but I need to explain it with a reaction mechanism, I also need a simpler explanation: -Method Extraction with solvents. These processes are based on the coefficient of distribution of lactic acid between water and various organic solvents. The Jenemann process describes a continuous countercurrent system using isopropyl ether as solvent. The process is expensive and dangerous because ether is flammable and forms explosive peroxides.
