Nhanganyaya
Tosylisocyanate, inozivikanwawo seTosylisocyanate. Iyi inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza p-toluenesulfonylisocyanate:
Hunhu:
-Kutaridzika: isina ruvara kana yakareruka yero mvura.
- Solubility: Soluble mune zvakajairika organic solvents, senge ethanol, dimethylformamide, nezvimwe.
- Kugadzikana: Kugadzikana, asi kusangana nemvura uye alkali yakasimba inofanira kudzivirirwa.
Shandisa:
Tosyl isocyanate inonyanya kushandiswa se reagent kana kutanga chinhu mune organic synthesis maitiro. Tosyl isocyanate inogonawo kushandiswa sechinhu chinokonzeresa uye boka rinodzivirira mumakemikari ekugadzira.
Nzira:
Nzira yekugadzirira ye toluenesulfonyl isocyanate inowanzowanikwa nekuita benzoate sulfonyl chloride ne isocyanate. Matanho chaiwo anosanganisira kuita kwe sulfonyl chloride benzoate ine isocyanate pamberi penheyo, mukamuri kana tembiricha yakaderera. Izvo zvinogadzirwa zvigadzirwa zvinowanzo kutorwa uye kucheneswa nenzira dzakadai seye solvent extraction uye crystallization.
Zvekuchengetedza
-Kusangana neganda uye maziso kunofanirwa kudziviswa panguva yekushanda kudzivirira kushatirwa kana kukuvara.
- Nzvimbo yekushanda inofanirwa kufefeterwa zvakanaka uye kudzivirira kufemesa mhute dzayo.
- Panguva yekuchengetedza uye kutakura, kusangana nehunyoro uye alkali yakasimba inofanira kudziviswa kudzivirira maitiro asina kuchengeteka.
-Tevedza maitiro ekuchengetedza akakodzera uye matanho uye pfeka zvakakodzera zvekuzvidzivirira nazvo paunenge uchishandisa nekubata tosyl isocyanate.
