Depolymerization of polyesters in sub- and supercritical water
Depolymerization behavior polyesters (poly(ethylene terephthalate) (PET) and poly(ethylene 2,6-naphthalene dicarboxylate) (PEN)) in suband supercritical water was investigated for the purpose of monomer recycling. In case of the depolymerization of PET, the yield of terephthalic acid (TPA) increased to 90 % with increasing reaction temperature up to 693 K while the maximum yield of ethylene gly...
متن کاملCatalytic Depolymerization of Alkali Lignin in Sub- and Super-critical Ethanol
The effects of reaction parameters on catalytic depolymerization of alkali lignin in suband super-critical ethanol were investigated using a high pressure autoclave, and the liquid oil and solid char products were characterized. The experimental data indicated that Rh catalysis, controlling reaction conditions at ethanol critical temperature (240 oC) and pressure (7.0 MPa), high ethanol/water r...

تجارت الکترونیکی شیوه اجرای مسئولیتها، تقابل با مشتریان و امور معمول عملیاتی در شرکتها را تغییر داده است. تجارت الکترونیکی در عمل تنها خرید و فروش کالاها را از طریق ابزار الکترونیک نمی باشد، بلکه تمام فعالیتهای لازم جهت انجام فرایند فروش را نیز در بر میگیرد. در اواخر دهه 1990 بسیاری از شرکتها فعالیتهای خود را به منظور دستیابی به مشتریان جدید و یا ارائه فرصتهای جدید به مشتریان موجود گسترش دادند...
Application of Sub-Critical Water Extraction in Pharmaceutical Industry
Sub-critical water extraction is a brand-new separation technology. This paper mainly discussed the principle, advantages of sub-critical water extraction, and its applications ranging from the medicinal plants traditionally used in Europe and Asia to produce pharmaceutical extracts (such as volatile oil, tannins, flavonoids, anthraquinone, lactone, etc.). Meanwhile, the prospect of sub-critica...
متن کاملHydrothermal Depolymerization of Polyesters and Polycarbonate in the Presence of Ammonia and Amines
Reaction conditions, temperature and pressure ranges, for various chemical recycling proc‐ esses of polyesters are sketched in Figure 1. So far, various recycling processes for polyesters have been investigated and developed, as reviewed by Paszun and Spychaj [1]: alcoholysis with methanol or ethanol, glycolysis with ethylene glycol or propylene glycol, alkali hydrolysis with sodium hydroxide, ...
