Isingeniso

Ingakwazi ukuncibilika lapho ishiswa ngesivinini esivamile futhi ibole ku-298 ℃ (ukuvalwa kweshubhu, ukushisisa ngokushesha). Ukuncibilika emanzini: 68g/l, empeleni okungancibiliki otshwaleni obubandayo ne-ether, kuncibilika ku-asidi engaphili; i-insoluble kuma-solvents ephilayo; incibilika kancane ku-benzene notshwala.
