Phase Process

Rigid polyurethane (RPU) foams have been successfully glycolyzed by using diethylene glycol (DEG) and crude glycerol (CG) as transesterification agents. However, DEG did not allow to achieve a split-phase process, obtaining a product with low polyol purity (61.7 wt %). On contrary, CG allowed to achieve a split-phase glycolysis improving the recovered polyol purity (76.5%). This is an important novelty since, up to now, RPUs were glycolyzed in single-phase processes giving products of low polyol concentration, which reduced the further applications. Moreover, the nanosilica used as filler of the glycolyzed foams was recovered completely pure. The recovered polyol successfully replaced up to 60% of the raw polyol in the synthesis of RPU foams and including the recovered nanosilica in the same concentration than in glycolyzed foam. Thus, the feasibility of the chemical recycling of this type of polyurethane composites has been demonstrated. Additionally, PU foams were synthesized employing fresh nanosilica to evaluate whether the recovered nanosilica has any influence on the RPU foam properties. These foams were characterized structurally, mechanically and thermally with the aim of proving that they met the specifications of commercial foams. Finally, the feasibility of recovering the of CG by vacuum distillation has been demonstrated.

Rate Of Accumulation

Ethylene glycols have been found to allow activation of purified preparations of human plasminogen. The activity of the enzyme formed, plasmin, was measured using TAMe (p-toluene-sulphonyl-L-arginine methyl ester) as a substrate. In 50% (v/v) solutions of these compounds at pH 7.6 and 30 °C, plasmin accumulated faster in diethylene and triethylene glycols than in glycerol, but in ethylene glycol no plasmin was found. When lower concentrations of ethylene glycol (from zero to 50%) and shorter times of incubation were used, plasmin was found. With equimolar solutions (4.3 M) of glycerol and the three glycols, only diethylene glycol showed a fast rate of accumulation of plasmin. A 50% triethylene glycol solution partially inhibited the rate of spontaneous activation but stabilized the plasmin formed and therefore enzyme accumulated. At room temperature more plasmin accumulated than at higher temperatures when plasminogen was incubated in 50% triethylene glycol solution, and no plasmin was found when plasminogen was incubated at pH 7.6, 30 °C, in 50% solutions of propylene glycols, several ethers of the ethylene glycols, several polymers of various glycols, and dioxane.

Nanosized particles of AFe2O4 compounds (A = Mn, Fe, Co, Ni, Zn) with spinel structure have been synthesized by precipitation from glycol solutions. Diethylene glycol (DEG) was used as high-boiling alcohol medium. Based on NMR studies, the peculiarities of the formation of nanoparticles in glycol solution using metal nitrates as initial reagents have been considered. For the synthesized compounds crystallographic, microscopical and magnetic investigations have been carried out.
