Tetrabureya / cas 4559-86-8-8 / tbu / nnnn tetrabureya

Kufotokozera kwaifupi:

Tetrabzurea (TBU) imakhala yopanda utoto wopaka chikasu cha chikasu. Ili ndi kusasinthika kwa mawonekedwe ndipo imadziwika chifukwa cha fungo lake, lomwe limatha kufotokozedwa ngati lokoma kapena lokoma pang'ono. Tbu amasungunuka mu ortic sodic ndipo ali ndi malire otsika.

Tetrabutyllureas 455-86-8-86-8 itha kugwiritsidwa ntchito kukonzekeretsa ma pulasitiki ndi okhazikika pa mankhwala ophera tizilombo, mankhwala osokoneza bongo, utoto, ndi pulasitiki.

Karata yanchito

Tetrabsuka (tbu)ndi mafuta makamaka amagwiritsidwa ntchito ngati zosungunulira ndikukonzanso mitundu yosiyanasiyana yamankhwala. Zambiri mwatsatanetsatane, chonde onani:

1. Zosungunulira mu synthesic synthesis:1,1,3-Tettabutylureya nthawi zambiri imagwiritsidwa ntchito ngati zosungunulira zachilengedwe, makamaka mu kapangidwe kazinthu zosiyanasiyana zachilengedwe. Kutha kwake kusungunuka kwa polar ndi polar kumapangitsa kuti ikhale yothandiza kwambiri pamakonzedwe a labotale.

2. Kutulutsa ndi kupatukana:Tetra-n-butylurea imatha kugwiritsidwa ntchito mu njira zamadzimadzi zamadzimadzi kuti zisanduke mankhwala osungirako zinthu. Zimakhala zothandiza kwambiri kuti zitheke ma ions a chitsulo ndi zinthu zachilengedwe zophatikizira.

3. Zoyeserera pamachitidwe a mankhwala:N, n, n ', n'-butylurea amatha kugwiritsidwa ntchito ngati chosinthika pamankhwala osiyanasiyana, kuphatikizapo kusinthana komwe kumachitika chifukwa cha exophilic.

4. Chothandizira chonyamulira:Mwa njira zina zothandizira, TBS itha kugwiritsidwa ntchito ngati chonyamula chonyamulira chonyamula kuti chizichulukitse kusungunuka kwake ndikukhala ndi mwayi.

5. Ntchito Zofufuzira:N, n, n ', n'-butylurea amagwiritsidwa ntchito m'maiko ofufuza, makamaka kafukufuku wokhudzana ndi kudyetsa, makamaka zakumwa za iyoc ndi minda ina yathupi ndi mankhwala.

Momwe mungasungire tetrabutyllurea?

Tetrabuntylurea (tbu) iyenera kusungidwa bwino kuti azikhala okhazikika ndikuletsa ngozi iliyonse yomwe ingachitike. Nawa maupangiri osungira tettrabureyea:

1. Chidebe:Sungani tetrabutyl urea mu chidebe chosindikizidwa kutilepheretsa kuipitsidwa ndi kutuluka. Chidebe chikuyenera kupangidwa ndi zinthu zomwe zikugwirizana ndi zosungunulira, monga galasi kapena pulasitiki ina.

2. Kutentha:Sungani tbu mu malo ozizira, owuma kutali ndi dzuwa ndi kutentha kwa dzuwa. Zoyenera, ziyenera kusungidwa kutentha kwa firiji, koma malo osungira amadalira malingaliro a wopanga.

3..Onetsetsani malo osungirako osungirako ali ndi mpweya wabwino kuti muchepetse zomangamanga za nthenga zilizonse zomwe zitha kumasulidwa.

4. Patulani zida zosagwirizana:Sungani tetrabtutyl urea kutali ndi oxidants amphamvu, ma asidi ndi zida zina zosagwirizana kuti zithetse zomwe zingawonongeke.

5. Zizindikiro:Mwachidziwikire zotengera zopezeka ndi dzina la mankhwala, ndende, chidziwitso chowopsa, ndi deti lolandila. Izi zimathandiza kuzindikira zinthu ndipo zimawoneka kuti zikuyenda bwino.

6. Kusamala:Tsatirani malangizo onse osungirako za chitetezo cha mankhwala ndi malangizo, kuphatikiza omwe amaperekedwa ndi malamulo anu kapena mabungwe am'deralo.

7. Kutaya:Ngati tetrabutyl urea ayenera kutayidwa, chonde tsatirani malamulo am'deralo okhudza kutaya zinyalala.

Nthawi zonse amatanthauza pepala la chitetezo chakuthupi (MSDS) la tetrabutyl urea wosungira mwachindunji ndi kuwongolera malingaliro.

Kuchenjeza nthawi yoyendera a tetrabutyllurea?

Mukamayendetsa tetrabutyl urea, mosamala mosamalitsa ayenera kumwedwa kuti awonetsetse chitetezo ndikutsatira malamulo. Izi ndi zina zofunika kuziganizira zomwe ziyenera kugwiritsidwa ntchito poyendera:

1. Kutsatira lamulo:Onetsetsani kuti kutumiza kumayenderana ndi malamulo adziko komanso apadziko lonse pokhudzana ndi mayendedwe onyamula zida zowopsa. Chongani ngati tetrabutyl urea amatchulidwa kuti ndi zinthu zowopsa ndikutsatira malangizo oyenera.

2. Ma Cantrang:Gwiritsani ntchito phukusi loyenerera lomwe limagwirizana ndi tetrabutyl urea. Mbaliyo iyenera kukhala yotayirira ndipo yopangidwa ndi zida zomwe zitha kupirira mankhwala a tbu. Onetsetsani kuti phukusi ndi lamphamvu mokwanira kuti muchepetse kuwonongeka.

3. Zilembo:Zolemba momveka bwino kuti pamunsi ndi dzina la mankhwala, chizindikiro chowononga, ndi chidziwitso chilichonse chothandiza. Izi zikuphatikiza kugwiritsa ntchito malangizo ndi chidziwitso chadzidzidzi.

4. Kuwongolera kutentha:Ngati ndi kotheka, gwiritsani ntchito tettobutyllurea pansi pa kutentha kwa kutentha kuti mupewe kuwonongeka kapena kusintha kwa katundu. Pewani kuwonetsedwa ndi kutentha kwambiri.

5. Pewani zinthu zosagwirizana:Onetsetsani kuti tetrabutylurea samatumizidwa palimodzi ndi zida zosagwirizana monga oxidals kapena ma asidi kuti musatengere zochita.

6. Zida Zaumwini (PPE):Ogwira ntchito omwe amaphatikizidwa paulendo akuyenera kuvala PPE yoyenera, monga magolovesi, magalasi, ndi zovala zoteteza kuti muchepetse kuwonekera kapena kutayikira.

7. Njira zadzidzidzi:Khalani ndi njira zadzidzidzi kuti muthane ndi ma spill kapena ngozi paulendo. Izi zimaphatikizapo kukonzekera kukhetsa mapira ndi othandizira choyamba.
