Abstract: Industrial depolymerization process of polyethylene terephthalate (PET) contained in artificial, natural and mixed dimethyl terephthalate (DMT) fibres by a first depolymerization of the PET in the presence of ethylene glycol and a catalyst (preferably sodium carbonate) to bis hydroxyethylene terephthalate (BHET), and subsequent transesterification of BHET solutions from the pressing of said artificial or natural fibres and from the washing of the same fibres. This process is characterized in that: in step a) the weight ratio of PET-containing fibres to ethylene glycol is between 0.3 and 4, preferably between 1.2 and 1.5; step b) comprises a step b-1) of pressing the final mixture and a step b-2) of washing the fibres from b1) with methanol or with the post-crystallization recovery solution of DMT, and in step c) the transesterification is carried out on the BHET liquid solution from the pressing b-1) and on that also containing methanol from washing the fibres of step b-2).

Abstract: A new class of multifunctional tracers has been synthesised for use in the oil industry, specifically during waterflooding operations. They are used either in a traditional way (i.e., mapping the connections of oilfield selections) or to provide information on important physical-chemical parameters (such as oil content, temperature and rock permeability) useful for optimizing the oilfield management and subsequent improvement/increase in oil extraction. The multifunctional tracers have a polymer chain having a plurality of units different from one another and recurring along the chain and having respective specific functionalities.
