hi.. macam mana nak buka cerita ya.. hmm, actually hoyeh ni post-graduate student tengah buat research pasal gelatin..duk syok2 buat, tetiba salah satu bahan penting dalam resepi research hoyeh ni abes.. oder la baru, tengok2 chemical tu dah tak disupply kat malaysia.. government dah tak bagi masuk sebab air-forbidden katanya.. hoyeh tak tahu nak buat apa sekarang sebab chemical tu sangat la penting..tak boleh tukar ke bahan lain, sebab kalau tukar kena repeat all over again.. research ni dah more than half way.. ada sesiapa tahu tak mana nak cari, or any idea..? sebab sangat sedih dan tension sebab stuck kat sini.. nama chemical tu "ethyl chloroformate" please..please..

comeynye bhn kimia ni: Ethyl chloroformate




nmpknye mcm bukan bahan yg mesra alam..sbb double bond Oxygen tu  boleh break ngan senang

info mengenai toxicnye bhn ni: http://www.inchem.org/documents/icsc/icsc/eics1025.htm


TT tak mende alternatif lain ker leh replace ethyl chlorormate ni


cuba try site ni: http://www.chemicalregister.com/products.asp
klu malaysia ni tak de supllier
amik supplier dr luar
& before that get approval dr supervisor...


arap membantu

tq dauswq..tapi masalahnya, gov dah tak benarkan ECF ni masuk malaysia dah.. dats why la takde supplier.. sebab b4 dis sy slalu beli ECF ni kat SIGMA.. pas PO kena reject, sy try other company,pun PO kna rject sbb bila dorang cek2 mmg da tak leh nak supply, sbb ECF ni smua dr luar.. and the latest is FISHER.. at first, dorang kata ada..then sy pn berbunga2 la hati ni..pastu dh dpt quotation, wat PO, once again kena reject sbb dorg kata takleh nak supply.. my supervisor ckp klu ad sape2 kt malaysia ni yg leh sintesis ECF ni dipersilakan lah.. then sy nak beli..

Kalau dah tak boleh masuk, apa lagi sintesis untuk kegunaan public. Since ianya boleh di sintesis, kenapa tak sintesis sendiri? chewah, mcm faham sgt aku plak hal hal chemical nie

yup,certain chemical memang susah nak dapat,so kalau dah company kat malaysia memang takde stok dlm simpanan,so its impossible sbb tak dibenarkan bawak masuk ke dlm negara...the only solution adalah synthesis sendiri, cuba cari kat online patent, search method for producing the ECF at the lab scale...


sy amat memahami...my probs bukan pasal takleh bawak masuk kat malaysia,tp takde yg sanggup jual dalam jumlah yg kecik, bl dah dapat jumpa tu baru terang sikit dunia,tu pun slagi takde PO,slagi tu tak tenteram,takut mula2 ckp boleh supply dlm small quantity tp lepas tu ckp tak leh pulak


good luck dlm pencarian
