Yɛ nu mli tsamɔ mli lɛ, akɛ maleic anhydride tsuɔ nii kɛfeɔ nu mli tsamɔ nibii. Ebaanyɛ ekɛ calcium kɛ magnesium ions ni yɔɔ nu mli lɛ afee ekome ni efee ŋmeii ni nyɛɛɛ atsɔ mli, ni no haa nu lɛ mli wamɔ baa shi. Abaanyɛ akɛ Maleic anhydride hu atsu nii ni akɛfee nibii ni tsiɔ ŋmeii anaa kɛ ŋmeii ni tsiɔ ŋmeii kɛ ŋmeii ni yɔɔ nu gbɛjianɔtoi amli lɛ anaa.
Yɛ nibii babaoo ni akɛtsuɔ nii yɛ mli lɛ fɛɛ sɛɛ lɛ, maleic anhydride lɛ yɛ acid ni efiteɔ nii, ni ekɛ nitsumɔ kɛ etoohe biɔ shweshweeshwefeemɔ he gbɛjianɔtoo ni mli wa.
