Munyaya yemakemikari echisikigo, kukosha kwezvinoderedza hakufanirwe kutaurwa zvakanyanya. Pakati pezvinhu zvakasiyana-siyana zvinoshandiswa pachinangwa ichi, acetyl chloride inoonekwa nekuda kwehunhu hwayo hwakasiyana uye kushanduka-shanduka. Iyi blog ichapa tarisiro yakadzama pamusoro pehunhu hweacetyl chloride, mashandisirwo ayo, uye basa rayo mukuderedza mapoka emabasa echisikigo.
Chii chinonzi acetyl chloride?
Acetyl chloride, fomura yemakemikari CH3COCl, iacid chloride inobva kuacetic acid. Imvura isina ruvara ine hwema hunopisa uye inoshanda zvakanyanya, kunyanya nemvura nedoro. Kuita uku kunoita kuti ive chinhu chakakosha mumhando dzakasiyana dzekuita kwemakemikari, kunyanya mukugadzirwa kwemamwe makemikari eorganic.
Basa reacetyl chloride mukuderedza reaction
Chimwe chezvishandiso zvikuru zveacetyl chlorideInoderedza makemikari emu organic. Inonyanya kushanda pakuderedza ma aldehydes, ketones uye chlorinated phthalides. Kugona kuderedza mapoka aya anoshanda kunoita kuti acetyl chloride ive chishandiso chakakosha kune vanoongorora makemikari.
Deredza aldehydes nemaketones
MaAldehydes (RCOH) nemaketone (RCOR) mapoka anoshanda zvakanyanya mumakemikari eorganic. Kuderedzwa kwemapoka aya kwakakosha pakugadzirwa kwealcohols nezvimwe zvinobva mairi.Acetyl chloridezvinogona kubatsira shanduko iyi nekupa maerekitironi, zvichinyatso shandura boka recarbonyl kuita boka rehydroxyl. Izvi hazvingoshandi chete, asi zvinogona kuderedza mapoka chaiwo ebasa pasina kukanganisa mamwe mapoka ebasa ari mumorekuru.
Naphthalenes dzine chlorine
Maophthalone ane chlorine ndeimwe mhando yemakomichi anogona kuderedzwa uchishandisa acetyl chloride. Makomichi aya anowanzo shandiswa mu pH indicators uye dyes. Maitiro ekuderedza anogona kushandura hunhu hwawo, zvichiita kuti anyatsokodzera kushandiswa kwakanangana. Nekushandisa acetyl chloride, ma chemistry anogona kuwana shanduko dzinodiwa uku achichengetedza kusimba kwechimiro chose.
Zvakanakira kushandisa acetyl chloride
1. Kusarudza:Chimwe chezvakanakira zvikuru kushandisa acetyl chloride semushonga wekuderedza huwandu hwezvinhu mumasero ndiko kusarudza kwayo. Inogona kunanga mapoka chaiwo emabasa pasina kukanganisa mamwe mapoka emabasa, zvichibvumira kugadziriswa kwakanyatsojeka kwemamorekuru akaomarara eorganic.
2. Kushanda zvakanaka:Mwero wekuita kweacetyl chloride unowanzo kuve wakakwira, zvichikonzera nguva yekusanganisa zvinhu nekukurumidza. Kushanda zvakanaka uku kunobatsira zvikuru mumaindasitiri uko nguva nemari zviri zvinhu zvakakosha.
3. Kuchinja-chinja:Acetyl chloride inogona kushandiswa mune zvakasiyana-siyana kunze kwekuderedza, kusanganisira acylation uye ester synthesis. Kuchinja-chinja uku kunoita kuti ive chinhu chinokosha mubhokisi rezvishandiso zvemakemikari wezvemakemikari.
Matanho ekuchengetedza
Kunyangwe zvakadaroacetyl chlorideInoshanda zvine simba, inofanira kubatwa nokungwarira. Inoparadza uye inogona kukonzera kutsva kwakanyanya painobata ganda kana maziso. Pamusoro pezvo, inoburitsa hydrochloric acid kana ikasangana nemvura, izvo zvinogona kuva nengozi. Nzira dzakakodzera dzekuchengetedza dzakakosha pakushanda nechinhu ichi, kusanganisira kushandisa michina yekudzivirira (PPE) uye kushanda munzvimbo ine mhepo yakanaka.
Acetyl chloridechinhu chinonakidza mumunda wemakemikari echisikigo, kunyanya sechinoderedza maaldehydes, ketones uye chlorinated phthalides. Kusarudza kwayo, kushanda kwayo zvakanaka, uye kushanduka-shanduka kunoita kuti ive chinhu chakakosha kune vanoongorora makemikari. Zvisinei, kuchengetedzeka ndiko kunonyanya kukosha pakubata zvinhu zvakadaro zvinoshanda. Sezvo tsvakiridzo yemakemikari echisikigo uye mashandisirwo azvo zvichiri kuramba zvichikura, acetyl chloride pasina mubvunzo icharamba ichiita basa guru mukugadzirwa nekugadzirisa makemikari echisikigo.
