Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izimpawu Eziyingozi I-Xn - Iyingozi
Amakhodi Engozi R21/22 – Kuyingozi ukuthinta isikhumba futhi uma ugwinyiwe.
R36/37 – Ukucasula amehlo kanye nesistimu yokuphefumula.
R40 – Ubufakazi obuncane bomphumela we-carcinogenic
Incazelo Yokuphepha I-S13 – Gwema ukudla, iziphuzo nokudla kwezilwane.
S23 – Ungawuphefumuli umhwamuko.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S46 – Uma ugwinywe, funa iseluleko sezokwelapha ngokushesha futhi ubonise lesi sitsha noma ilebula.

Isingeniso

Inephunga elifana ne-camphor. Amazolo aba yi-dimer, ekhishwa emoyeni ukuze ikhiqize i-4,4, 6-trimethyl-1, i-cyclohexanedione. Incibilika otshwaleni, i-ether ne-acetone, ixubene nezinyibilikisi eziningi eziphilayo, ukuncibilika emanzini: 12g/L (20°C). Kukhona amathuba okuba nomdlavuza. Kukhona ukucasuka okukhihliza izinyembezi.
