Intshayelelo
I-Monomethyl subrate, i-chemical formula C9H18O4, i-organic compound. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
- I-Monomethyl subrate lulwelo olungenambala kunye nevumba elithambileyo leziqhamo kubushushu begumbi.
-Ubuninzi bayo bu malunga ne-0.97 g / mL, kwaye indawo yokubilisa i malunga ne-220-230 ° C.
- I-Monomethyl subrate ine-solubility efanelekileyo kwaye inokunyibilika kwizinto ezininzi ze-organic solvents, ezifana ne-alcohols kunye ne-ethers.
Sebenzisa:
- I-monomethyl subrate ingasetyenziselwa ukudibanisa ezinye iikhompawundi eziphilayo, ezifana nencasa, imifuno, amayeza kunye nedayi.
-Inokusetyenziswa kwakhona kwizicelo zoshishino ezifana ne-solvents, i-lubricants kunye ne-plasticizers.
Indlela yokulungiselela:
-Indlela eqhelekileyo yokulungiselela i-Monomethyl subrate yi-esterification reaction ye-suberic acid kunye ne-methanol. Ukusabela ngokuqhelekileyo kuqhutyelwa phantsi kweemeko ze-acidic kusetyenziswa i-acid catalyst efana ne-asidi ye-sulfuric okanye i-agent ye-methylating efana ne-methylsulfuric acid.
Ulwazi ngoKhuseleko:
I-Monomethyl subrate ityhefu ephantsi, kodwa kusafuneka ithathele ingqalelo ukusetyenziswa ngokukhuselekileyo.
-Kuphephe ukudibana nolusu kunye namehlo. Ukuba kukho uqhagamshelwano, hlambulula ngokukhawuleza ngamanzi amaninzi.
-isetyenziselwa ukugcina iimeko ezilungileyo zokungenisa umoya, ukuphepha ukuphefumla umphunga wayo.
- I-monomethyl subrate iyatsha kwaye kufuneka igcinwe kude nomlilo kunye nobushushu obuphezulu.
-Ukugcinwa kufuneka kutywinwe, kwindawo epholileyo neyomileyo, kude nomlilo kunye ne-oxidizing agents.
