School And in separating components of a homogeneous mixture of two liquids which have boiling points (PE) different in the laboratory? It is necessary to assemble the apparatus as shown in figure: Photo: Icon Audiovisual The process is essentially similar to the laboratory manufacturing process. Puts a small amount of the mixture to be separated in the distillation flask. Starts heating. In fractional distillation the vapors of the two liquids are forced to pass between the glass marbles (obstacles) column. Only substance vapor of lower boiling overcomes obstacles and passes to the liquid state in the condenser. After the condenser, the liquid flows into the Kitazato, where it is collected. The substance of higher boiling point condenses in contact with the glass marbles and returns to the flat-bottomed flask. To account of the high consumption of oil, refineries mo-dernizaram to, at the same time, decrease the losses and increase the production of motor fuels. Thus, the oil extracted in Venezuela may be different than oil from the offshore Campos (RJ). And derivatives are different? Just are obtained in different amounts. The characteristic construction technique determines those of each refinery fuels to be produced in greater quantity. This can be translated as refining structure. The refining structure differs depending on the domestic consumption requirements of each country. In Brazil, after the rationalization measures adopted by the government in 1975, the gasoline, which had precedence over the other derivatives, yielded its place to fuel oil and diesel oil.

Škola I u rastavljanje homogenom smjesom dvije tekućine koje imaju vrelišta (PE) različite u laboratoriju? Potrebno je sastaviti aparaturu kako je prikazano na slici: Foto: Icon audiovizualnu politiku Proces je u biti sličan procesu laboratorijske proizvodnje. Stavlja malu količinu smjese treba odvojiti u tikvicu za destilaciju. Počinje zagrijavanje. U destilacijom pare dviju tekućina su prisiljeni da prođe između staklenih kuglica (prepreke) stupaca. Samo tvar pare niže kuhanjem nadilazi prepreke i prelazi u tekuće stanje u kondenzatoru. Nakon kondenzatora, tekućina teče u Kitazato, gdje se prikupljaju. Tvari visokog vrelišta kondenzira u kontaktu sa staklenim mramor i vraća se u ravnim dnom tikvice. Da u obzir visoku potrošnju nafte, rafinerije mo-dernizaram na, u isto vrijeme, smanjiti gubitke i povećati proizvodnju motornih goriva. Dakle, ulje izvađen iz Venezuele može biti drugačiji od nafte iz offshore Campos (RJ). A derivati se razlikuju? No samo su dobiveni u različitim iznosima. Karakteristična tehnika gradnje određuje one rafinerijske goriva će se proizvoditi u većoj količini. To se može prevesti kao poboljšanje strukture. Rafiniranje struktura razlikuje ovisno o domaćoj potrošnji zahtjevima svake zemlje. U Brazilu, nakon što mjere racionalizacije usvojila vlada u 1975, benzin, koja je imala prednost u odnosu na ostale derivate, dala je svoje mjesto na loživo ulje i dizel ulje. sintetske kemije
