Gas Chromatography of Ethanol in Alcoholic Beverages Questions

(1) What is the purpose of n-propanol in this experiment and why is it so cruical to accuracy and precision to this experiment?

(2) Why were there only two chromatographic peaks (Ethanol + N-propyl) seen in the data collected for all of the analytical standards?

Please answer both in detail, thank you!

EDIT: Procedure below:

1) Using an adjustable pipet, transfer 1.00mL of the liquor (66% proof Fireball) and 0.500mL of n-propanol into a 10.00mL volumetric flask. Dilute to the mark with nanopure water.

2)5.00% v/v Ethanol standard (one per group): Pipet 0.500 mL of absolute ethanol and 0.500mL of n-propanol into a 10.00mL volumetric flask using an adjustable pipet. Dilute to the mark with nanopure water.

3) Set up the gas chromatograph for an isothermal anaylsis at 90 C. Inject 1 uL of the 5% ethanol standard until consistant results are obtained.

4) Sequentially analyze 1uL of both your unknown sample and the 5.00% ethanol standard.

5) Estimate the concentration of the ethanol by comparing area ratios to the 5% ethanol standard. Be sure to correct for the dilution factor used to prepare the sample. Prepare 3 addtional ethanol standards suitable for calibration of your particular alchol sample.

6) Injections of the 1uL should be used for all FOUR ethanol standards and unknown (fireball 66% proof). Each standard and sample should be run three times and use the data to answer questions and create graphs.

The graphs had 2 peaks. One smaller peak of Ethanol and one larger peak of N-Propanol.

When validating an Autoclave, what are the steps in the qualification study?

a) What is the strength and limitation od the four methods for finding the roots of equations: (1) the graphical method; (2) the bisection method; (3) the simple (one-point) iteration method and (4) the Newton Raphson method. You can use graphs or example to enhance your explanation.

b) Discuss the strength and limitation of (1)naive Gauss elimination; (2)Gauss elimination with partial pivoting, (3) Jacobi iteration and (4) Gauss-Siedel method in solving the set of linear equations, in terms of error and convergence.

What is a major economic advantage of producing therapeutic proteins in plants rather than in bioreactors filled with microbes or mammalian cells?

The liquid-phase reaction

    A---> B + C

takes place in a series of two CSTRs with an overall conversion of 0.75. Two newly purchased CSTRs are added to the series. The volumetric flow rate is then increased in order to keep the overall conversion at 0.75.

(a) List all your assumptions.
(b) If the original flow rate was 150 L/min, determine the new flow rate (L/min).

1.           Your site is contaminated with 158 kg gasoline (C₇H₁₆, MW = 100 g/mol) Calculate the amount of O₂, N, and P needed.

Calculate the enthalpy and entropy of the saturated vapor of isobutane at 360 K from the following information:

1. Table 6.1 provides the compression factor information (Z values) for isobutane vapor.

2. The vapor pressure of isobutane at 360 K is 15.41 bar.

3. Consider H0g = 18 115.0 J mol ^ -1 and S0g = 295.976 J mol ^ -1* K ^ -1 for the reference state of an ideal gas at 300 K and 1 bar.

4. The heat capacity of the ideal gas of the isobutane vapor at the temperatures of interest:

Cp / R = 1.7765 + 33.037x10 ^ -3T (T / K)

Use the Table 6.1: Z compressibility factors for isobutane. (text book "Introduction Termodymanic in chemical engineering edition 7")
