Phenylurea Product Description
6-Amino-1,3-dimethyluracil ikemikari yemakemikari ine molecular formula C6H9N3O.Iyo organic compound ndeye uracil mhuri.Mushonga wacho une uracil ring structure ine amino group (NH2) yakabatanidzwa kune 6-nzvimbo uye maviri methyl mapoka (CH3) akabatanidzwa kune 1- uye 3-nzvimbo.Iyo kemikari chimiro inogona kuratidzwa se: inotyisa ||CH3--C--C--C--N--C--CH3 ||ammonia 6-Amino-1,3-dimethyluracil inhengo yepakati mukugadzirwa kwemishonga yakasiyana-siyana yemishonga.Inoshandiswa zvakanyanya mukugadzira antiviral uye antitumor zvinodhaka.Ndiyo yekutanga zvinhu zve synthesis ye nucleoside analogs yekurapa hutachiona hwehutachiona uye cancer.
Mukuwedzera, 6-amino-1,3-dimethyluracil inoshandiswawo mumunda wezvizoro.Inogona kushandiswa sechinhu chinongedzo murunako uye zvigadzirwa zvekuchengeta zvega senge makirimu eganda uye lotions.Zvimiro zvaro zvinoita kuti ive yakakodzera kushandiswa seganda uye moisturizer.Kuchengetedza kwakakodzera kwekuchengetedza kunokurudzirwa kana uchibata 6-amino-1,3-dimethyluracil.Chengetedza munzvimbo inotonhorera, yakaoma kure nemoto kana kupisa.Pamusoro pezvo, zvinokurudzirwa kupfeka zvidziviriro zvemunhu senge magurovhosi uye magirazi kudzivirira kusangana kwakananga nekomboni.
Mukupedzisa, 6-amino-1,3-dimethyluracil inhengo yehupenyu inoshandiswa sepakati mukati mekugadzirwa kwemishonga yemishonga, kunyanya antiviral uye antitumor zvinodhaka.Inoshandiswawo mucosmetics nekuda kweganda rekugadzirisa zvinhu.Chengetedzo dzekuchengetedza dzinofanirwa kuteedzerwa pakubata iyi komputa.

Phenylurea Kushandiswa uye Synthesis
| Chemical Properties | Makristasi asina mavara-akafanana netsono kana pfumbu-chena.Melting point 147°C(kuora), inonyungudika mumvura inopisa, doro rinopisa, ether, ethyl acetate uye acetic acid. |
| Uses | Phenylureas inowanzoshandiswa mishonga yesora inoiswa muvhu pakudzora huswa nemasora madiki-seeded broadleaf. |
| Uses | Phenyl urea inoshandiswa mune organic synthesis.Inoshanda senge ligand inoshanda yepalladium-catalyzed Heck uye Suzuki maitiro earyl bromides uye iodides. |
| Kugadzirira | Phenylurea inogadzirwa nekuita kweaniline uye urea.Isa urea, hydrochloric acid uye aniline muhari yekupindura, kupisa uye kumutsa, reflux pa 100-104 ° C kweawa imwe, wedzera mvura uye simbisa, inotonhorera, sefa, geza keke resefa nemvura, uye woomesa kuti uwane chigadzirwa chakapedzwa. ye phenylurea. |
| Application | Phenyl urea mushonga wezvipembenene, mvura, ine chepfu inoratidzika semvura yakanyungudutswa kana kuti yakaturikwa mumutakuri wemvura.Iine chero akati wandei ane hukama makomisheni (Diuron, Fenuron, Linuron, Neburon, Siduron, Monuron) zvakatorwa kubva kuurea.Mutakuri ane mvura emulsifiable.Toxic nekufemba, kupfekwa kweganda, kana kunwa. |
| General Description | Chinhu chakasimba kana mvura inobatwa pane yakaoma mutakuri.Upfu hwakanyorova.Iine chero ipi zvayo yezvigadzirwa zvine hukama (Diuron, Fenuron, Linuron, Monuron, Neburon, Siduron) zvakatorwa kubva kuurea.Toxic nekufemba, kupfekwa kweganda, kana kunwa.Tora zita rehunyanzvi remushonga chaiwo kubva pamapepa ekutumira uye bata CHEMTREC, 800-424-9300 kuti uwane ruzivo rwemhinduro. |
| Reactivity Profile | Organic amides/imides inopindirana neazo uye diazo komisheni kugadzira magasi ane muchetura.Magasi anopisa anoumbwa nekuita kweorganic amides/imides ane simba rekudzikisa maajenti.Amides zvigadziko zvisina kusimba (zvisina simba kupfuura mvura).Imides hainyanyi kukosha asi uye inonyatsoita nemabhesi akasimba kugadzira munyu.Kureva kuti vanogona kuita seasidhi.Kusanganisa maamide neanobvisa mvura mumuviri maajenti akadai seP2O5 kana SOCl2 anoburitsa nitrile inoenderana.Kupisa kwemakomponi aya kunoburitsa maokisidi akasanganiswa enitrogen (NOx).Iine chero akati wandei ane hukama makomisheni (Diuron, Fenuron, Linuron, Neburon, Siduron, Monuron) zvakatorwa kubva kuurea. |
| Dambudziko rehutano | Muchetura wakanyanya, unogona kuuraya kana ukafemerwa, ukamedzwa kana kunyudzwa nemuganda.Dzivisa chero kusangana kweganda.Mhedzisiro yekubata kana kufemesa inogona kunonoka.Moto unogona kuburitsa anoshatirisa, anoparadza uye/kana magasi ane muchetura.Kuyerera kunobva pakudzivirira moto kana kuti dilution mvura inogona kuita ngura uye/kana ine chepfu uye ichikonzera kusvibiswa. |
| Moto Hazard | Chisingabatiki, chinhu pachacho hachipisi asi chinogona kuora pakudziya kuti chibudise hutsi hunoparadza uye/kana hune muchetura.Midziyo inogona kuputika kana ichidziya.Runoff inogona kusvibisa nzira dzemvura. |
| Kuchenesa Nzira | Gadzirisa urea kubva mumvura inofashaira (10mL/g) kana amyl doro (m 149o).Pukuta muovheni inopisa kusvika 100o.Iyo 1:1 resorcinol yakaoma ine m 115o (kubva kuEtOAc/*C6H6).[Beilstein 12 H 346, 12 II 204, 12 III 760, 12 IV 734.] |
