Abstract
Inventia se refera la un derivat de benzen, utilizat ca agent purtator de caldura, caracterizat prin aceea ca are structura corespunzatoare formulei generale: (vezi formula) în care n are valoarea 1...5 si este un produs lichid cu aspect de ulei de culoare galben-brun, cu greutate specifica la 20 degree C de 0,977...0,978 g/cm3, caldura specifica la 25 degree C de 0,35 kcal/kg, vîscozitate la 20 degree C de 300...350 Ps, punct de aprindere prin metoda Marcusson de 208 degree C, punct de ardere de 227 degree C. Procedeul de obtinere a derivatului conform inventiei se caracterizeaza prin aceea ca se aduc în reactie cu benzenul cu dicloretanul, în raport molar de 4:1 pîna la 6:1, temperatura de reflux, în prezenta unei cantitati de 0,04...0,07 mol/1 clorura de aluminiu, produsul de reactie fiind supus apoi distilarii la presiunea atmosferica, pentru îndepartarea excesului de benzen si apoi la 5...10 torr si 140...200 degree C, pentru separarea fractiunilor volatile care pot fi, eventual recirculate în proces.The invention relates to a benzene derivative used as a heat carrier, characterized in that it has the structure corresponding to the general formula: (see formula) wherein n is 1 ... 5 and is an oil-like liquid product yellow-brown color, specific gravity at 20 degrees C of 0.977 ... 0.978 g / cm3, specific heat at 25 degree C of 0.35 kcal / kg, viscosity at 20 degrees C of 300 ... 350 ps, ignition by the Marcusson method of 208 degrees C, a combustion point of 227 degrees C. The process for obtaining the derivative according to the invention is characterized in that it is reacted with benzene with dichloroethane in a molar ratio of 4: 1 to 6: 1, reflux temperature, in the presence of 0.04 ... 0.07 mol / l aluminum chloride, the reaction product being subjected to distillation at atmospheric pressure to remove excess benzene and then to 5 ... 10 torr and 140 ... 200 degrees C, to separate the volatile fractions which may be, e.g., entwally recirculated in the process.
