Intshayelelo

I-Dimethyl succinate (i-DMDBS ngokufutshane) yi-organic compound. Oku kulandelayo kukwazisa ngobume, ukusetyenziswa, indlela yokwenza, kunye nolwazi lokhuseleko lwe-DMBS:

Umgangatho:
1. Ukubonakala: ulwelo olungenambala olunevumba elikhethekileyo.
2. Ubuninzi: 1.071 g/cm³
5. I-Solubility: I-DMBS ine-solubility efanelekileyo kwaye inokunyibilika kwiintlobo ezahlukeneyo ze-solvents eziphilayo.

Sebenzisa:
1. I-DMBS isetyenziswa kakhulu kwiipholima zokwenziwa njengeplastiki, izithambisa kunye nezithambisi.
2. Ngenxa yokuzinza kwayo kakuhle ngokomzimba kunye neekhemikhali, i-DMBS ingasetyenziselwa njengeplastiki kunye ne-softener ye-synthetic resins, iipeyinti kunye neengubo.
3. I-DMBS isetyenziswa ngokuqhelekileyo ekulungiseleleni iimveliso zerabha ezithile, ezifana nesikhumba sokwenziwa, izihlangu zerabha kunye nemibhobho yamanzi.

Indlela:
Ukulungiswa kwe-DMBS ngokuqhelekileyo kufumaneka nge-esterification ye-succinic acid kunye ne-methanol. Ukulungiselela indlela ethile, nceda ujonge kuncwadi olufanelekileyo lwe-organic synthesis.

Ulwazi ngoKhuseleko:
1. I-DMBS ilulwelo olunokutsha, kwaye kufuneka kuthathelwe ingqalelo ukuphepha ukudibana nomlilo ovulekileyo kunye nokushisa okuphezulu xa ugcina kwaye uyisebenzisa.
3. Xa uphethe kwaye ugcina i-DMBS, amanyathelo afanelekileyo okungenisa umoya kufuneka athathwe ukuphepha ukuphefumla imiphunga yayo.
4. I-DMBS kufuneka igcinwe kude nobushushu obuphezulu, amadangatye avulekileyo kunye ne-oxidants, kwaye igcinwe kwindawo eyomileyo nepholileyo.
