Benzene from Coal-Tar Light Oil: Washed and Rectified, Lunge 1887
The light oil from coal tar (everything below about 170 °C) is rectified, washed with the strongest sulfuric acid and then weak caustic soda, and rectified again by steam in a column: the part up to 110 °C is 90-per-cent benzol. Washed and rectified once more, then frozen and pressed, it gives pure benzene (Lunge, 1887). Benzene is toxic and carcinogenic, and its vapour catches fire easily.

Okuqukethwe okuyingozi
Le blueprint iqukethe izinqubo eziyingozi. Ngena ngemvume bese uvula okuqukethwe okuyingozi kuzilungiselelo ze-akhawunti yakho ukuze ubone iziqondiso zesinyathelo ngesinyathelo.
NgenaLe blueprint yenza
Ama-blueprint ahlobene
Lama-blueprint abelana ngolwazi — amasu, izinto noma izimiso
CC0 Isizinda Somphakathi
Le blueprint ikhishwe ngaphansi kwe-CC0. Ukhululekile ukukopisha, ukuguqula, ukusabalalisa, nokusebenzisa ngaphandle kwemvume.
Sekela uMenzi ngokuthenga imikhiqizo nge-Blueprint yabo IKhomishane Yomenzi kumiswe ngabathengisi, noma dala inguqulo entsha yale Blueprint bese uyifaka njengoxhumaniso ku-Blueprint yakho ukuze wabelane ngemali engenayo.
