Mawu Oyamba
Monomethyl subrate, mankhwala chilinganizo C9H18O4, ndi pawiri organic. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
- Monomethyl subrate ndi madzi opanda mtundu okhala ndi fungo lofooka la zipatso kutentha kutentha.
-Kuchuluka kwake kumakhala pafupifupi 0.97 g/mL, ndipo kuwira kwake kumakhala pafupifupi 220-230 ° C.
- Monomethyl subrate ili ndi kusungunuka kwabwino ndipo imatha kusungunuka muzinthu zambiri zosungunulira, monga ma alcohols ndi ethers.
Gwiritsani ntchito:
- Monomethyl subrate ingagwiritsidwe ntchito kupanga zinthu zina zakuthupi, monga zokometsera, zitsamba, mankhwala ndi utoto.
-Itha kugwiritsidwanso ntchito m'mafakitale monga zosungunulira, mafuta opangira mafuta ndi mapulasitiki.
Njira Yokonzekera:
-Njira yokonzekera yodziwika bwino ya Monomethyl subrate ndi kudzera mu esterification reaction ya suberic acid ndi methanol. Zomwe zimachitika nthawi zambiri zimachitika pansi pa acidic pogwiritsa ntchito chothandizira cha asidi monga sulfuric acid kapena methylating agent monga methylsulfuric acid.
Zambiri Zachitetezo:
- Monomethyl subrate low kawopsedwe, komabe muyenera kulabadira kugwiritsa ntchito moyenera.
-Pewani kukhudza khungu ndi maso. Ngati pali kukhudzana, muzimutsuka nthawi yomweyo ndi madzi ambiri.
-Mu ntchito kukhala wabwino mpweya mikhalidwe, kupewa inhalation ake nthunzi.
- Monomethyl subrate imatha kuyaka ndipo iyenera kusungidwa kutali ndi moto komanso kutentha kwambiri.
-Kusungirako kumayenera kusindikizidwa, pamalo ozizira komanso owuma, kutali ndi moto ndi oxidizing agents.
