Polyphthalamides are a class of polymers used in several components of automobile engines, and are produced using benzene-1,4-dioic acid (terephthalic acid) and an aliphatic diamine. Draw the repeating unit of the polyphthalamide that uses hexane-1,4- diamine Он NH2 но. weww H2N Hexane-1,6-diamine Benzene-1,4-dioic acid (Terephthalic acid)

what is the theoretical yield for this experiment?
ORGANIC POLYMERS: THE SYNTHESIS OF NYLON Nylon's outstanding characteristic in the textile industry is its versatility. It can be made strong enough to stand up under the punishment tire cords must endure, fine enough for sheer, high fashion hosiery, and light enough for parachute cloth and backpacker's tents. Nylon is used both alone and in blends with other fibers, where its chief contributions are strength and abrasion resistance. Nylon washes easily, dries...

JVCUDDL/64/1/649?response-content-dispositioninline Introduction: It is estimated that approximately 150 million metric tons of plastics are currently circulating in our global system of oceans and waterways. This seems like a fairly generic "big! number", and it's difficult to understand the scale of the problem without converting it to something more relatable. A standard empty plastic water bottle weighs approximately 12.7 g....

for this experiment, what is the balanced chemical equation and
mechanism?
Experimental Procedure a) Reagent Preparation (mix in hood): 1. In a 125mL Erlenmeyer dissolve 1 mL of the sebacyl chloride in 50 mL of hexane. Label the Solution as SC 2. In a 50mL Erlenmeyer dissolve 2.5 mL of 1,6-hexanediamine in 25 mL of 3% sodium hydroxid Label the solution as diamine. (The 3% NaOH solution will be provided) b) Nylon Synthesis 1. Using a 10mL graduate cylinder take...

QUESTIONS 1. What is the purpose of the sulfuric acid (yes, it's a catalyst, but why is it a catalyst? What is it doing that makes the reaction possible? Would the reaction just go slower without it, or would the reaction not go at all? Why?) 2. If isobutyl alcohol (2 methyl propanol) is used instead of tert butyl alcohol, a mixture of products is obtained. One the products is the same as the product obtained with the tert butyl...

2. Briefly explain why ethanol, and not hexane, was used as a solvent in this reaction? 3. Why it is necessary to filter the crude coupling product through a column of anhydrous MgSO4? 4. Briefly explain why aryl bromides and iodides, rather than aryl chlorides or fluorides, are typically used as substrates in Pd-catalyzed coupling reactions. 5. Propose a synthesis for the molecule A shown below, using benzene, phenyl boronic acid, tert-butyl bromide and any inorganic reagents needed. A retrosynthetic...

PROBLEM 1 A nickel-titanium alloy is. used to make components for jet turbine aircraft engines. Cracking is a potentially serious problem in the final part because it can lead to non-recoverable failure. A test is run at the parts produced to determine the effect of four factors on cracks. The four factors are A pouring temperature Btitanium content C = heat treatment method D amount of grain refiner used Two replicates of a 2 design...
