Mylar, synthesis

Use Synthesis of terephthalic acid for polyester resins and fibers ( Dacron, Mylar, Terylene ), vitamin and pharmaceutical syntheses, insecticides. 

Similarly, many reactors with integrated mixers and other functionality can be manufactured on one substrate to form, e.g., a combinatorial synthesis platform. Such microfluidic platforms may approach the complexity of VLSI electronic circuits, see e.g. [64], which gives an example fabricated by soft lithography (imprinting) in the polymer PDMS or [65], which gives an example in laser-machined laminated Mylar sheets. The combinatorial aspect of these examples consists in mixing chemicals in different ratios to achieve concentration series in a discrete way (i.e. a different concentration for each microchannel) which are subsequently used in a chemical reaction on the same microfluidic chip. 

Bofh alkyl groups are oxidized to —COOH groups. The product is terephthalic acid, one of two monomers required for fhe synthesis of Dacron polyester and Mylar (Section 29.5B). 

Figm 9 PIXE spectrum and fitfor a perdeuterated polyethylene sample. Data were obtained with 0.5 gC of 2.00 MeV H ions delivered to the sample surface. A 75 pm Mylar filter was used to prevent backscattered protons from reaching the detector. The size of the peaks corresponds to -700 and 4500 ppm (by mass) for S and Ca, respectively, probably due to the catalyst support agent used in the synthesis. Fitting was carried out with GuPIX software.
