Tetrabutylurea/cas 4559-86-8/TBU/NNNN TETRABUTYLUREA

Kufotokozera Kwachidule:

Tetrabutylurea (TBU) nthawi zambiri ndi madzi achikasu otuwa. Ili ndi mawonekedwe a viscous ndipo imadziwika ndi fungo lake, lomwe limatha kufotokozedwa kuti ndi lofatsa kapena lokoma pang'ono. TBU imasungunuka mu zosungunulira za organic ndipo imakhala yochepa kwambiri.

Tetrabutylurea cas 4559-86-8 angagwiritsidwe ntchito pokonza mapulasitiki ndi okhazikika a mankhwala ophera tizilombo, mankhwala, utoto, ndi mapulasitiki.

Kugwiritsa ntchito

Tetrabutylurea (TBU)ndi pawiri makamaka ntchito monga zosungunulira ndi reagent mu zosiyanasiyana ntchito mankhwala. Zambiri mwatsatanetsatane, chonde onani zotsatirazi:

1. Zosungunulira mu organic synthesis:1,1,3,3-Tetrabutylurea nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira za organic reaction, makamaka pakuphatikizika kwamitundu yosiyanasiyana yachilengedwe. Kutha kwake kusungunula zinthu zambiri za polar komanso zopanda polar zimapangitsa kuti zikhale zothandiza kwambiri pama labotale.

2. Kuchotsa ndi Kupatukana:TETRA-N-BUTYLUREA itha kugwiritsidwa ntchito pochotsa madzi-zamadzimadzi kuti alekanitse zinthu kutengera kusungunuka kwake. Ndiwothandiza makamaka pochotsa ayoni ena achitsulo ndi organic mankhwala kuchokera ku zosakaniza.

3. Reagents mu Chemical reactions:N,N,N',N'-Tetra-n-butylurea itha kugwiritsidwa ntchito ngati reagent muzochitika zosiyanasiyana zamankhwala, kuphatikiza machitidwe okhudzana ndi nucleophilic substitution ndi kusintha kwina kwachilengedwe.

4. Catalyst carrier:Munjira zina zothandizira, TBU itha kugwiritsidwa ntchito ngati chothandizira chonyamulira kuti ipititse patsogolo kusungunuka kwake komanso kusinthika pakusakanikirana kwamachitidwe.

5. Ntchito Zofufuza:N,N,N',N'-TETRA-N-BUTYLUREA imagwiritsidwa ntchito m'malo ochita kafukufuku, makamaka kafukufuku wokhudzana ndi kusungunuka, zakumwa za ayoni ndi zina zakuthupi ndi zamankhwala.

6. Polima Chemistry:N,N,N',N'-tetrabutyl-;tetrabutyl-ure itha kugwiritsidwanso ntchito mu chemistry ya polima ndipo itha kugwiritsidwa ntchito ngati zosungunulira kapena zowonjezera polima.

Momwe Mungasungire Tetrabutylurea?

Tetrabutylurea (TBU) iyenera kusungidwa bwino kuti ikhale yokhazikika komanso kupewa zoopsa zilizonse. Nawa malangizo osungira tetrabutylrea:

1. Chotengera:Sungani tetrabutyl urea mu chidebe chotsekedwa kuti muteteze kuipitsidwa ndi kutuluka kwa nthunzi. Chidebecho chiyenera kupangidwa ndi zinthu zomwe zimagwirizana ndi zosungunulira za organic, monga galasi kapena mapulasitiki.

2. Kutentha:Sungani TBU pamalo ozizira, ouma kutali ndi kuwala kwa dzuwa ndi kutentha. Moyenera, ziyenera kusungidwa kutentha kwa firiji, koma zosungirako zenizeni zingadalire malingaliro a wopanga.

3. Mpweya wabwino:Onetsetsani kuti malo osungiramo ali ndi mpweya wabwino kuti muchepetse kuchulukana kwa nthunzi iliyonse yomwe ingatuluke.

4. Siyanitsani kuzinthu zosagwirizana:Sungani tetrabutyl urea kutali ndi okosijeni amphamvu, ma asidi ndi zinthu zina zosagwirizana kuti mupewe zoopsa zilizonse.

5. Chizindikiro:Lembetsani momveka bwino zotengera zomwe zili ndi dzina lamankhwala, ndende, zidziwitso zangozi, ndi tsiku lomwe mwalandira. Izi zimathandiza kuzindikira zinthu ndikuwonetsetsa kugwidwa kotetezeka.

6. Chitetezo:Tsatirani malangizo ndi malamulo onse okhudzana ndi chitetezo chosungiramo mankhwala, kuphatikiza zomwe zaperekedwa ndi bungwe lanu kapena malamulo amdera lanu.

7. Kutaya:Ngati Tetrabutyl Urea ikufunika kutayidwa, chonde tsatirani malamulo akumaloko okhudza kutaya zinyalala zowopsa.

Nthawi zonse tchulani Material Safety Data Sheet (MSDS) ya Tetrabutyl Urea kuti musunge ndikuwongolera momwe mungasamalire.

Chenjezo pamayendedwe okhudzana ndi Tetrabutylurea ?

Ponyamula tetrabutyl urea, njira zodzitetezera ziyenera kuchitidwa kuti zitsimikizire chitetezo komanso kutsatira malamulo. Zotsatirazi ndi zina zofunika kuziganizira poyenda:

1. Kutsata Malamulo:Onetsetsani kuti katunduyo akugwirizana ndi malamulo a m'deralo, a dziko lonse komanso apadziko lonse okhudza kayendetsedwe ka zinthu zoopsa. Yang'anani ngati tetrabutyl urea yaikidwa ngati zinthu zowopsa ndipo tsatirani malangizo oyenera.

2. Kuyika:Gwiritsani ntchito zolembera zoyenera zomwe zimagwirizana ndi tetrabutyl urea. Chidebecho chiyenera kukhala chosadutsika komanso chopangidwa ndi zinthu zomwe zimatha kupirira mankhwala a TBU. Onetsetsani kuti zoyikapo ndi zolimba kuti zisawonongeke panthawi yoyendetsa.

3. Chizindikiro:Lembetsani paketiyo momveka bwino ndi dzina lamankhwala, chizindikiro chowopsa, ndi chidziwitso chilichonse chokhudza chitetezo. Izi zikuphatikizapo malangizo okhudza momwe angagwiritsire ntchito ndi mauthenga okhudzana ndi ngozi.

4. Kuwongolera Kutentha:Ngati ndi kotheka, yendetsani Tetrabutylrea pansi pazikhalidwe zoyendetsedwa ndi kutentha kuti mupewe kuwonongeka kapena kusintha kwa zinthu. Pewani kutenthedwa kwambiri.

5. Pewani Zida Zosagwirizana:Onetsetsani kuti Tetrabutylurea siitumizidwa pamodzi ndi zinthu zosagwirizana monga ma oxidants amphamvu kapena ma acid kuti muteteze zomwe zingachitike.

6. Zida Zodzitetezera Payekha (PPE):Ogwira ntchito zoyendera ayenera kuvala ma PPE oyenera, monga magolovesi, magalasi, ndi zovala zodzitchinjiriza kuti achepetse kukhudzidwa ngati kutayikira kapena kutayikira.

7. Njira Zadzidzidzi:Pangani njira zadzidzidzi zothana ndi kutaya kapena ngozi panthawi yamayendedwe. Izi zikuphatikizapo kukonza zida zotayira ndi zida zoyambira.
