Application

Tetrabutylurea (TBU)Iyo yakaomeswa inonyanya kushandiswa seyakagadziriswa uye yakasarudzika mune akasiyana emakemikari emakemikari. Zvimwe zvakadzama ruzivo, ndapota tarisa kuteverwa:

1. Solvent mu organic synthesis:1,1,3,3-tetrabutylurure inowanzoshandiswa sechigadzika che organic maitiro, kunyanya mune synceis yemakomputa akasiyana siyana. Kugona kwayo kunyungudutsira huwandu hwakawanda hwekuputika uye zvisiri zvepolar zvinhu zvinoita kuti zvive zvinobatsira kwazvo mumarabhoritari marongero.

2. Kubvisa uye kupatsanurwa:Tetra-n-butylurea inogona kushandiswa mumvura-yemvura yekubvisa maitiro ekuzviparadzanisa mishonga yakaparadzana zvichienderana nesarudzo yavo. Izvo zvinonyanya kushanda mukubvisa mamwe masimbi ioni uye organic makomputa kubva mumixtures.

3. Reagents mumakemikari maitiro:N, n, n ', n'-tetra-n-butylurea inogona kushandiswa seyakajairwa nemakemikari maitiro, kusanganisira maitiro anosanganisira tucleophilic kutsiva uye mamwe organic shanduko.

4. Catalyst Carrier:Mune mamwe maitiro ezvekutengesa, TBU inogona kushandiswa seyakajairwa inotakura inotakura svikiro yekuwedzera iyo solubility uye maitiro mumusanganiswa wekuita.

5. Zvikurudziridzo zvekutsvaga:N, n 'n', n'-tetra-n-butylurea inoshandiswa munzvimbo dzekutsvaga, kunyanya kutsvagisa kunobatanidza zvinoitika, ionic zvinwiwa uye mamwe minda yemuviri uye yemakemikari.

6. Polymer Chemistry:N, n, n ', n'-tetrabutyl-; tetrabutyl-ure inogona zvakare kushandiswa muPolymer Chemistry uye inogona kushandiswa solvent kana kuwedzera muPolymer synthesa.

Maitiro Ekuchengetedza Tetrabutylurea?

Tetrabutylurea (TBU) inofanira kuchengetwa zvakanaka kuti irambe yakasimba uye kudzivirira chero njodzi dzinogona kuitika. Heano mamwe mimwe mirayiridzo yekuchengetedza Tetrabutylurea:

1. Mudziyo:Chengetedza tetrabutyl urea mumudziyo wakasungwa kudzivirira kusvibiswa uye kubuda kwemvura. Iyo mudziyo unofanirwa kugadzirwa nezvinhu zvinowirirana ne organic sol soles, senge girazi kana dzimwe mapurasitiki.

2. Tembiricha:Chengetedza tbu munzvimbo inotonhorera, yakaoma kure kubva kune yakananga zuva uye kupisa masosi. Zvakakodzera, inofanira kuchengetwa pamhepo tembiricha, asi mamiriro ezvinhu ekuchengetedza anogona kutsamira pakurudziro yemugadziri.

3. Ventilation:Ita shuwa nzvimbo dzekuchengetera dzakanyatsovhurwa kuti uderedze kuvakwa kwe chero vaputi vanogona kusunungurwa.

4. Kuparadzaniswa kubva kune zvisingaenderane zvinhu:Chengetedza Tetrabutyl Urea kure kubva kune yakasimba oxidants, acids uye zvimwe zvinhu zvisingaenderane kuti udzivise chero zvine ngozi maitiro.

5. Label:Zviripachena zvemanyorerwo emidziyo nemakemikari zita, kusangana, nzara nengozi, uye risiti rekutambira. Izvi zvinobatsira kuona zvinhu uye nechokwadi chekubata chakachengeteka.

6. Kuchengetedza Kuchengetedza:Tevedza zvese zvakakodzera makemikari ekuchengetedza nhungamiro uye mirau, kusanganisira izvo zvinopihwa neyako institution kana mitemo yemuno.

7. Kuraswa:Kana Tetrabutyl Urea Urea inoda kuraswa, ndapota tevedzera mitemo yemuno maererano neine ngozi marara.

Gara uchitaura kune iyo yekuchengetedza data data sheet (msds) yeTetrakutyl Urea yerea yekukwana kwekuchengetedza uye kubata mazano.

Inyonganidzo panguva yekufambisa pamusoro peTetrabutylurea?

Paunenge uchitakura Tetrabutyl Urea, mamwe manyawi anofanira kuendeswa kuti ave nechokwadi chekuchengetedza uye kutevedzera nemirairo. Izvi zvinotevera kufunga kwakakosha kunofanirwa kufungwa panguva yekufambisa:

1. Regulatory kutevedzera:Ita shuwa kuti kutumirwa kunoenderana nemitemo yemuno, yenyika uye yenyika ine chekuita nezvekufambisa kwemidziyo ine ngozi. Tarisa uone kana Tetrabutyl Urea inogadziriswa sechinhu chine ngozi uye tevera zvakakodzera nhungamiro.

2. Kurongedza:Shandisa zvakakodzera kurongedza zvinoenderana neTetrabutyl Urea. Iyo mudziyo unofanirwa kuve wakabikwa uye wakagadzirwa nezvinhu zvinogona kutsungirira zvimiro zvemakemikari zveTBU. Ita shuwa kuti kurongedza kwakasimba zvakakwana kuti udzivise kukuvara panguva yekufambisa.

3. Label:Nyora zvakajeka kurongedza nezita remakemikari, hazard chiratidzo, uye chero ruzivo rwakakodzera rekuchengetedza. Izvi zvinosanganisira kubata mirayiridzo uye emergency yekukurumidzira ruzivo.

4. Tembiricha kutonga:Kana zvichidikanwa, kutakura tetrabutylurea pasi pekudziya-kudzorwa mamiriro ekudzivirira kudzivirirwa kana shanduko mune zvivakwa. Ngwarira kuratidzwa nekunyanyisa kupisa.

5. Ngwarira zvisingaenderani zvinhu:Ita shuwa kuti Tetrabutylurea haina kuendeswa pamwe chete nezvinhu zvisingaenderane seyakajairika oxidants kana acids kudzivirira chero zvingangoita zvingangoitika.

6. Kuchengetedza Kwemunhu (PPP):Vashandi vanobatanidzwa mukufambisa vanofanirwa kupfeka zvakakodzera ppe, senge magurovhosi, goggles, uye zvipfeko zvekudzivirira kuti zviongorore muchiitiko chekupaza kana kusvetuka.

7. Maitiro Ekurumidzira:Kukudziridza maitiro ekukurumidzira kuti ubate nematambudziko kana tsaona panguva yekufambisa. Izvi zvinosanganisira kugadzirira kibhedhi uye yekutanga rubatsiro zvekushandisa.
