Matter insoluble in petroleum ether (40°C.-60°C.):
Ábhar dothuaslagtha in éitear peitriliam ( 40°C-60°C)
Matter insoluble in petroleum ether (40°C.-60°C.):
Éitear peitriliam (PE) fiuchphointe 40-60 °C (sainmheáchan 0,65).
Petroleum ether (PE) boiling point 40– 60 °C (specific gravity 0,65).
Déanfar an toilleadh bailithe seo TCE a ionadú trí thoilleadh 30 ml éitear peitriliam ag fiuchphointe 40-60 °C a chur sa tonnadóir deighilte.
This collected volume of TCE shall be substituted by adding a volume of 30 ml of petroleum ether boiling point 40– 60 °C into the separation funnel.
Nuair a dhéantar cóireáil air leis na heisníocháin beinséin. éitear peitriliam, clóraform, aicéatón, eatánól nó meatánól oibríonn sé ar nós bicsin, agus tugann sé an t-imoibriú Carr-Price uaidh.
Treated by the elutants benzene, petroleum ether, chloroform, acetone, ethanol or methanol it behaves like bixin and also gives the Carr-Price reaction described in sub-paragraph (b) of paragraph 1 above.
