TetramethLuanine / TMG CAS 80-70-6

Incazelo emfushane:

I-TetramethLuanine (i-TMG) iwuketshezi olungenamibala lokushisa egumbini lokushisa. Inephunga elinamandla le-ammoniacal. I-TMG isisekelo esiqinile se-organic esivame ukusetshenziswa ezinhlelweni ezahlukahlukene zamakhemikhali, kufaka phakathi i-catalyst ku-organic synthesis. Isakhiwo saso samangqamuzana siqukethe i-nucleus ye-guanidine namaqembu amane we-methyl, anikezela ngezakhiwo ezihlukile.

I-Tetramethylguanine (TMG) iyancibilika kakhulu emanzini futhi izixazululo eziningi ze-organic, kubandakanya notshwala nokuphatha. I-solubility yayo emanzini kungenxa yenhlangano yayo, evumela ukuthi ihlangane kahle ngama-molecule wamanzi.

Isicelo

I-1.TetramethLuanidine ingasetshenziselwa ama-polyurethane Foam Catalysts.

I-2.tetramethLuanine nayo ingahle isetshenziswe njenge-nylon, uboya kanye namanye amaprotheni ament.

I-3. I-Catalyst ekuhlolweni kwe-organic: I-TMG imvamisa isetshenziswa njengesisekelo esinamandla futhi i-catalyst ekuphendukeni okune-organic, njengokungena esikhundleni se-nucleophilic kanye nokusabela okunciphisayo.

I-4. Ukusabela kwamakhemikhali: Kusetshenziselwa ukuhlanganisa amakhompiyutha ahlukahlukene ahlukahlukene, kufaka phakathi izidakamizwa nama-agrochemicals.

I-5. I-electrolyte kumabhethri: I-TMG ingasetshenziswa njenge-electrolyte ezinhlotsheni ezithile zamabhethri, ikakhulukazi kumasethingi ocwaningo.

I-6. Ukulungiswa kwe-PH: Ngenxa yemvelo yayo ye-alkaline, i-TMG ingasetshenziswa ukulungisa i-PH ngezinqubo zamakhemikhali.

7. Izicelo zocwaningo: I-TMG isetshenziswa ezinhlelweni ezahlukahlukene zocwaningo, kubandakanya nezifundo ezibandakanya izindlela zokuphendula kanye nokuthuthukiswa kwezindlela ezintsha zokwenziwa.

Ukubeka

Egcinwe esitolo sokugcina esomile futhi emotweni.

1. Isitsha: Gcina i-TMG esitsheni esivalwe ukuvimba nokuhwamuka. Sebenzisa iziqukathi ezenziwe ngezinto ezihambelana nezisekelo eziqinile.

2. Ukushisa: gcina i-TMG endaweni epholile, eyomile kude nokukhanya kwelanga okuqondile nokushisa. Ukushisa kwegumbi kuvame ukufaneleka, kepha kufanele kugcinwe ngaphansi kuka-25 ° C (77 ° F) noma nini lapho kungenzeka.

I-5. Ilebula: Faka ilebula ngokucacile iziqukathi ngegama lamakhemikhali, okuhlushwa, nanoma yiluphi ulwazi olufanele lwengozi.

Ingabe i-tetramethylguanine iyingozi kubantu?

I-Tetramethylguanine (TMG) ingaba yingozi emzimbeni womuntu uma kungathathwanga izinyathelo zokuphepha okufanele. Nawa amanye amaphuzu asemqoka mayelana nobuthi bayo nokuphepha kwawo:

1. Ukucasulwa: I-TMG ingacasuka esikhunjeni, emehlweni naseqenjini lokuphefumula. Ukuxhumana ngqo no-liquid kungadala ukushiswa kwamakhemikhali noma ukucasuka.

2. Ukuphefumula: Ukuphefumula kwe-TMG Vapor kungadala ukucasuka okuphefumula neminye imiphumela emibi.

3. Ukungenisa: Ukungenisa kwe-TMG kungaba yingozi futhi kungadala ukucasulwa kwesisu noma eminye imiphumela emihle.

4 Sebenza endaweni enomoya owanele noma usebenzise i-fume hood ukuze unciphise ukuvezwa.

I-5. Usizo lokuqala: Uma kuvezwa izidakamizwa, thatha izinyathelo zokuqala zosizo lokuqala, ezinjengokuchofoza indawo ethintekile ngamanzi futhi ufuna ukwelashwa uma kunesidingo.

Izeluleko lapho umkhumbi uTetramethLuanidine?

Lapho uhambisa iTetramethLuanine (TMG), kufanele kuthathwe ezinye izinyathelo zokuphepha ukuze kuqinisekiswe ukuphepha nokuhambisana nemigomo. Nayi eminye imininingwane ebalulekile okufanele uyinake:

1. Ukulandela umthetho wokulawula: Bheka futhi ulandele imithetho yendawo, kazwelonke, neyamazwe omhlaba ngokuhamba kwezinto zokuhamba zempahla eyingozi. I-TMG ingahle ihlukaniswe njengento eyingozi, ngakho-ke qiniseka ukuthi yonke imibhalo yokuthumela inembile futhi iphelele.

2. Ukupakisha: Sebenzisa izinto ezisebenza kahle zokufaka ezihambelana ne-TMG. Iziqukathi kufanele zivuze futhi zenziwe ngezinto zokwakha ezingamelana nezimpawu zamakhemikhali. Sebenzisa izimpawu zesibili ukuvikela ukuvuza ngesikhathi sokuhamba.

3. Ilebula: Faka ilebula ngokucacile ukufakwa ngegama lamakhemikhali, uphawu lwengozi, nanoma yiluphi ulwazi lokuphepha olufanele. Lokhu kufaka phakathi ukuphendula imiyalo nemininingwane yokuxhumana eziphuthumayo.

I-4. Ukulawulwa kokushisa: Qinisekisa ukuthi izimo zokuthumela zigcina izinga lokushisa elizinzile, njengoba amazinga okushisa athe xaxa angathinta ukuqina kwe-TMG.

I-6. Imodi Yezokuthutha: Khetha indlela efanele yokuhamba (umhlaba, umoya, ulwandle) ohambisana nemithetho yempahla eyingozi. Qiniseka ukuthi imoto yezokuthutha ifakwe imishini edingekayo yokuphatha izimpahla eziyingozi ngokuphepha.

7. Izinqubo eziphuthumayo: Nikeza imininingwane ngezinqubo eziphuthumayo uma kwenzeka kuchitheka noma ukuvuza ngesikhathi sokuhamba. Qinisekisa ukuthi abasebenzi ababandakanyeke kwezokuhamba baqeqeshelwe ukuphatha izinto eziyingozi.
