Dimethyl karubone CAS 616-38-6
Dimethyl karubone, izwi nka DMC, ni amazi adafite ibara, abonerana kandi afite impumuro ikaze ku bushyuhe bw'icyumba. Ubucucike bwayo (d204) ni 1.0694, aho ishongesha ni 4°C, aho ishyuha ni 90.3°C, aho ishyuha ni 21.7°C (ifunguye) na 16.7°C (ifunze), aho igaragara (nd20) ni 1.3687, kandi irashya kandi ntigira uburozi. Ishobora kuvangwa n'ibintu byose bishongesha nk'ibinyobwa, ketone, na esters mu rugero urwo arirwo rwose kandi irashonga gato mu mazi. Ishobora gukoreshwa nk'ikintu gitera methylating. Ugereranyije n'ibindi bintu bitera methylating, nka methyl iodide na dimethyl sulfate, dimethyl karubone ntabwo ifite uburozi bwinshi kandi ishobora kwangirika.

Dimethyl karubone (DMC) ifite imiterere yihariye ya molekile (CH3O-CO-OCH3). Imiterere yayo ya molekile irimo amatsinda ya karubone, methili, methoxy na karubone. Kubwibyo, ishobora gukoreshwa cyane mu bikorwa bya organic synthesis nka karubone, methylation, methoxylation na karubone. Ifite imikorere myinshi cyane. Ikoreshwa cyane cyane nk'ingufu za karubone na methylation, inyongeramusaruro ya lisansi, n'ibikoresho fatizo byo gukora polycarbonate (PC). Umusaruro munini wa DMC wateye imbere hamwe n'uburyo bwo gukora polycarbonate butari fosgene. Imikoreshereze yayo ni iyi ikurikira:
1. Ubwoko bushya bw'umusemburo udahumanya cyane bushobora gusimbura ibintu nk'ibinyabutabire nka toluene, xylene, ethyl acetate, butyl acetate, acetone cyangwa butanone mu nganda zikora amarangi n'ubutare. Ni ikintu kibisi cyangiza ibidukikije.
2. Umuti mwiza wa methylating, umuti wa karubonelating, umuti wa hydroxymethylating n'umuti wa methoxylating. Ukoreshwa cyane mu bijyanye na antioxydants mu biribwa, ibirinda ibimera, nibindi. Ni ibikoresho fatizo bya shimi bikoreshwa cyane.
3. Uburyo bwiza bwo gusimbura imiti ihumanya cyane nka fosgene, dimethyl sulfate, na methyl chloroformate.
4. Guhuza polycarbonate, diphenyl carbonate, isocyanate, n'ibindi.
5. Mu buvuzi, ikoreshwa mu gukora imiti igabanya ubwandu, imiti igabanya ububabare n'imiti igabanya ububabare, imiti ya vitamine, n'imiti ikoreshwa mu mitsi yo hagati.
6. Mu miti yica udukoko, ikoreshwa cyane cyane mu gukora methyl isocyanate, hanyuma igakoreshwa mu gukora imiti imwe n'imwe ya karubomate n'imiti yica udukoko (anisole).
7. Inyongeramusaruro za lisansi, electrolytes za batiri ya lithiamu, nibindi.
