    摘要： Rubber, particularly crumb rubber from the recycling of tyres, is processed to effect partial or high levels of dissociation of rubber vulcanate network, in particular to form bituminous compositions in which the treated rubber, carbon black and other additives released are stably dispersed. Bitumen, hydrocarbon oil and liquid rubber are used to effect penetration, swelling and compatibilization of the rubber particles, following which thermal energy and mechanical energy are applied to initiate breakdown of the vulcanized structure of the rubber particles and the formation of at least partially dissociated rubber vulcanate network. Such treated rubber may be further reacted and combined for employment in the production of stabilized polymer modified bitumen composition.

    摘要： Provided is a method of recycling a waste resin composition containing a synthetic resin and organic impurities. A method of manufacturing a dihydroxy compound from a waste resin composition, the method including, a step (a1) in which an alkaline solution containing a first solvent, water, and a waste resin composition containing a resin having at least two constitutional units selected from the group consisting of general formulae (1) to (4) set forth below:




    is treated to give a reaction solution containing a first solvent and a mixture of dihydroxy compounds containing a first dihydroxy compound selected from the group consisting of general formulae (1') to (4') set forth below:




    and at least one other dihydroxy compound selected from the group consisting of the general formulae (1') to (4'); and a step (b1) in which the first dihydroxy compound is crystallized from a crystallization solution obtained by adding a second solvent to the reaction solution, wherein a difference between the solubility of the first dihydroxy compound at 25°C in the second solvent and the solubility of the other dihydroxy compound at 25°C in the second solvent (solubility of the other dihydroxy compound minus solubility of the first dihydroxy compound) is greater than or equal to 0.1 g/(10 mL).

    摘要： Disclosed is a commercially advantageous method for obtaining a monomer by performing a depolymerization reaction of a polyamide. Specifically disclosed is a method for obtaining a monomer through a depolymerisation reaction of a polyamide, wherein the depolymerization reaction is performed in the presence of a hydrocarbon solvent. In addition, the depolymerization reaction is performed in the presence of water. The ratio of water relative to the total mass of the hydrocarbon solvent and water is not more than 30 % by mass. The depolymerization reaction can be carried out without using a catalyst. Preferably, the depolymerization reaction is performed at a temperature not less than 300°C and not more than 420°C.
