Figure 1 The structure of 2,4,5-Trichlorophenol The synthesis of 2,4,5-Trichlorophenol Method 1: Protected compound (1.0 equiv) was dissolved in MeOH/THF (1:1) in a sealed vial and stirred with thiophenolate resin 1 (1.45 mmol/g, 0.2 equiv). The reaction was heated as described he...
others circular or tubular fabrics.The structure of the fabric is flexible and varies with the gauge of the machine,the type of yarn,and the tension that the yarn is being held whilst it is knitted.Some machine kint shaped garment parts on fully fashioned knitting machines,but most of[...
In single phase, only one liquid is flowing through the nozzle to form fibers with a single structure. In co-axial mode, fibers can be developed as core-shell structures — especially when encapsulation is desired — or in split structures known as Janus fibers. Multi-axial phase is the ...
