NOTES TO STUDENTS
? Check carefully the submission date and the instructions given with the
assignment. Late assignments will not be accepted.
? Ensure that you give yourself enough time to complete the assignment by the due
date.
? You must take responsibility for managing your own time effectively.
? If you are unable to hand in your assignment on time and have valid reasons such
as illness, you may apply (in writing) for an extension.
? Failure to achieve a PASS grade will results in a REFERRAL grade being given. ? Take great care that if you use other people’s work or ideas in your assignment,
you properly reference them in your text and any bibliography.
? When you refer to the work of other authors in your assignment, you must

ASSESSMENT
Outcome/ Skill P14.2 Discuss factors affecting the selection of a chemical process for the product Criteria Evidence Pass Assessment Feedback Assess P14.3 Examine physico-chemical aspects of an industrial process Evaluate the key parameters of the reaction which determine the choice of sulfonation to the linear alkylbenzene sulfonates in manufacturing synthetic detergents (e.g. temperature, acid strength, reaction time, and ratio of oleum-to-alkylate etc.) P14.2.2 Describe and Describe and analyse the analyse the influence influence of required of required post-reaction separation and post-reaction purification processes(e.g. separation and dilution, phase separation, purification processes neutralization) P14.2.3 Evaluate the Evaluate the impact of co- and impact of co- and side-products on the overall side-products on the profitability of the process(e.g. overall profitability of nonlinear/branched alkyl the process sulfonates) P14.3.1 Explain how Explain the spray-drying energetics equilibrium process in manufacturing and yield, rates, phase detergents forementioned in equilibrium and detail separations influence the selected industrial process P14.2.1 Evaluate the parameters of the chemical reaction which determine the choice of route to the product __________________________________________________
