In this research contribution, the primary objective was to enhance the crystallization behavior of poly (ethylene terephthalate) (PET).

MS-NW-6813 dimethyl terephthalate C10H10O4 (Mass of molecular ion: 194) Source Temperature: 260 °C Sample Temperature: 190 °C Reservoir, 75 eV

PET (polyethylene terephthalate) has good transparency, corrosion resistance, gas barrier properties and mechanical properties, and is widely used in beverage bottles, fabrics, food packaging ...

in representative deuterated NMR solvents are described in Figure 1 below. The third goal, and the focus of this document, is to provide guidance regarding the use and limitations of dimethyl terephthalate (DMTP) as an ISRM for qNMR analysis.

ABSTRACT: High-resolution NMR spectra of poly(ethylene terephthalate-iso phthalate) are measured by the use of tris(dipivalomethanato)europium as a shift reagent.

Enzymatic polyethylene terephthalate (PET) recycling processes are gaining interest for their low environmental impact, use of mild conditions, and specificity. Furthermore, PET hydrolase enzymes...

2010年9月5日 · 1 H NMR spectrum from purity determination of dimethyl terephthalate (B) using 100% pure acetanilide (A) as a primary reference standard. The areas of the signals at 8.1 ppm (B) and 2.0 ppm (A) were used for purity calculation.

1973年1月1日 · Here we describe a standing the crystallization of polyethylene terephthalate (PETP) by means of the NMR impulse method and show that it can give informational additional to the usual kinetic characteristics, i.e. about changes in …
