11 N Ethoxycarbonyl 4 Piperidylidene 8 Chloro 6 11 Dihydro 5h Benzo 5 6 Cyclohepta 1 2187628

/in /by

11-[N-ethoxycarbonyl-4-piperidylidene]-8-chloro-6,11-dihydro-5H-benzo-[5,6]-cyclohepta-[1,2-b]-pyridine (C22H23CIN2O2) is a nonsedative antihistamine, known as loratadine and marketed as Claritin. The preperation of the active pharmaceutical ingredient (API) is described in U.S. 4,282,233 (to Schering). The patent describes reacting 16.2g of 11-[N-methyl-4-piperidylidene]-8-chloro-6,11-dihydro-5H-benzo-[5,6]-cyclohepta-[1,2-b]-pyridine (C20H21CIN2) in 200ml of benzene with 10.9g of ehtylchloro formate (C3H5CIO2) for 18 hours. The mixture is cooled, poured into ice water, and seperated into aquaeous organic phases. The organic layer is washed with water and evaporated to dryness. The residue is triturated (ground to a fine powder) with pertroleum ether and recrystallized from isopropyl ether.
a.) What is the reaction byproduct?b.) The reaction appears to be carried out under conditions that maximize both selectivity and conversion (long time at low temperature), as might be expected given the cost of the raw material. If the conversion is 99.9% and the selectivity for the desired ethoxycarbonyl substituted compound is 100%, how much excess ethylchloroformate remains at the end of the reaction?c.) What fraction of the ethylchloroformate feed is lost to waste products?d.) Assuming that the volumes of water and isopropyl ether used in the quenching, washing and recrystallization steps are the same as the initial solvent volume, and that none of these materials are reused in the process, estimate the total mass of the waste material produced per kg of the API.e.) If the recovery (plant yield) of the API from the washing and recrstallization steps is 92%, estimate the feed flow rates of 11-[N-methyl-4-piperidylidene]-8-chloro-6,11-dihydro-5H-benzo-[5,6]-cyclohepta-[1,2-b]-pyridine and ehtylchloroformate required to produce a batch of 10kg of the API.f. How much API could be produced per batch in a 3.8m^3 (1000 US gal) reactor?
g. What would be the advantages and disadvantages of carrying out the other process steps in the same vessel?

12 The Student Government Association At Middle Carolina University Wanted To Demon 1307998

/in /by

12.   The Student Government Association at Middle Carolina University wanted to demon- strate the relationship between the number of beers a student drinks and their blood alcohol content (BAC). A random sample of 18 students participated in a study in which each participating student was randomly assigned a number of 12-ounce cans of beer to drink. Thirty minutes after consuming their assigned number of beers a member of the local sheriff’s office measured their blood alcohol content. The sample information is reported below.

Use a statistical software package to answer the following questions.

a.   Develop a scatter diagram for the number of beers consumed and BAC. Comment on the relationship. Does it appear to be strong or weak? Does it appear to be positive or inverse?

b.  Determine the correlation coefficient.

c.   At the .01 significance level, is it reasonable to conclude that there is a positive rela- tionship in the population between the number of beers  consumed  and  the BAC? What is the p-value?

12 A Fixed Income Money Manager Has A Bond Portfolio With A 70 Percent Allocation To 1733286

/in /by

12. A fixed income money manager has a bond portfolio with a 70 percent allocation to longterm bonds and a 30 percent allocation to short-term bonds. The portfolio is currently valued at $75 million. The manager wishes to reduce the long-term bonds allocation to 55 percent and increase the short-term bonds allocation to 45 percent for a period of three months. The modified duration of the long-term bonds is 7.5 and of the short-term bonds is 4.5. A bond futures contract that expires in three months is priced at $95,750 and has a modified duration of 6.25. Assume that the modified duration of cash equivalents is 0.25. Also assume that interest rates that drive long-term and short-term bond prices have a yield beta of 1 with respect to interest rates that drive the bond futures market. A. Show how the manager can achieve his goals by using bond futures. Indicate the number of contracts and whether the manager should go long or short. B. After three months, the short-term bonds are down 5.63 percent and long-term bonds are down 9.38 percent. The bond futures price is $88,270. Compare the market value of the portfolio using futures to adjust the allocation with the market value of the same portfolio using direct bond trading to adjust the allocation.
