Intangiriro
3,5-difluorobenzaldehyde ni ifumbire mvaruganda hamwe na formula ya chimique C7H4F2O. Ibikurikira nubusobanuro bwimiterere, imikoreshereze, imyiteguro namakuru yumutekano yikigo:
Ibyiza: 3,5-difluorobenzaldehyde ni ibara ritagira ibara ryumuhondo ryoroshye rifite umunuko udasanzwe. Ifite ubucucike bwa 1.383g / cm³, aho gushonga kwa 48-52 ° C, hamwe no guteka 176-177 ° C. 3,5-difluorobenzaldehyde ntishobora gushonga mumazi, ariko igashonga mumashanyarazi kama nka Ethanol, ether, na benzene.
Gukoresha: 3,5-difluorobenzaldehyde isanzwe ikoreshwa nkigihe gito muri synthesis. Irashobora gukoreshwa muguhuza ibinyabuzima bitandukanye bya fluor birimo ibinyabuzima, cyane cyane mubisubizo byimiti byinjiza atome ya fluor muri molekile kama. Byongeye kandi, irashobora kandi gukoreshwa nkigihe cyo guhuza imiti, imiti yica udukoko n amarangi.
uburyo bwo gutegura: uburyo bwo gutegura bwa 3,5-difluorobenzaldehyde burashobora kuboneka mugukora methanol ya 3,5-difluorobenzyl hamwe na acide aldehyde reagent (nka acide trichloroformic, nibindi). Uburyo bwihariye bwubukorikori bushobora kwifashishwa mu gitabo cyitwa Organic Synthesis Handbook hamwe nibitabo bifitanye isano.
Amakuru yumutekano: 3,5-difluorobenzaldehyde ni imiti kandi igomba gukoreshwa neza. Irakara kandi ikabora kandi irashobora kwangiza amaso, uruhu hamwe na sisitemu yubuhumekero. Ibikoresho bikwiye byo kurinda umuntu nka goggles, gants na ngabo zo mu maso bigomba kwambarwa mugihe cyo gukoresha. Kurikiza imyitozo yumutekano wa laboratoire hanyuma ubike, ufate kandi ujugunye uruganda neza. Mugihe uhuye nimpanuka cyangwa kuribwa, shakisha ubuvuzi bwihuse kandi utange amakuru akenewe kwa muganga.
