The structure of Kodel polyester that is formed by transesterification of dimethyl terephthalate with 1,4-di ( hydroxymethyl ) cyclohexane is to be drawn. Concept introduction: Transesterification process results in the formation of different ester and alcohol by the reaction between the alcohol and ester present as reactant. In this process strong acids catalyse the reaction by donation a proton to the carbonyl group, results in the formation of more potent electrophile and the bases catalyse the reaction removes the proton from the alcohol, results in the formation of more nucleophilic. Polyesters are the polymers that consist of ester functional group in the main polymer chain. Kodel is type of polyester used in the manufacture of thread.

3) The following molecule, chloral is a common precursor to chloral hydrate, an acetal type molecule that was a first-generation anesthetic. Draw a mechanism that accounts for tis formation and speculate why it does not require the use of an acid catalyst, like most hemiacetal and acetal reaction: (10 pts) H H₂O

You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Your organisation strives to ensure that >99.97% of bags of umami powder produced conforms to specification. What performance process index value is required to achieve this process yield? Calculate PPK using the following formula: Ppk = (USL – mean)/3 σ Ppk = (mean -LSL)/ 3 σ
