Ishishini lokuvuna njengomvelisi oyingcali, singathanda ukukubonelela nge-Ammonium Formate CAS 540-69-2. Kwaye siya kukubonelela ngeyona nkonzo ilungileyo emva kokuthengisa kunye nokuhanjiswa ngexesha. I-Ammonium Formate (HCOONH4) I-CAS: I-540-69-2 i-preservative i-antiseptic egqwesileyo yokutya, i-flavour kunye neziphuzo, kodwa ayinayo i-antioxidant effect.
Isaphulelo somgangatho wehoyilesi Ammonium Formate CAS 540-69-2. Ishishini lokuvuna yi-Ammonium Formate CAS 540-69-2
Icandelo lokuQala: Intshayelelo yeMveliso
I-Ammonium Formate (HCOONH4) I-CAS: I-540-69-2 i-preservative i-antiseptic egqwesileyo yokutya, i-flavour kunye neziphuzo, kodwa ayinayo i-antioxidant effect. I-Vitamin C (i-Vitamin C) ineempawu zokunciphisa ezinokuphelisa amaqela e-nitroso abangela umhlaza kunye ne-radicals yamahhala ebangela ukuguga, ngoko i-anti-aging, i-anti-cancer, i-anti-oxidant, i-scurvy, i-anti-fatigue, i-anti. -ukudumba, kunye neziphumo zokubulala iintsholongwane. I-Ammonium Formate (HCOONH4) I-CAS: I-540-69-2 yinto egqwesileyo ye-anti-oxidant yokugcina ukutya, i-astes kunye neziselo.

Icandelo leSine: Ukusetyenziswa
I-Ammonium Formate (HCOONH4) I-CAS: I-540-69-2 ingasetyenziswa kwishishini lamachiza okanye isetyenziswe njengeejenti zokuhlalutya.
Inxalenye yesihlanu:Uyifumana njani
1. Ithathwe kwi-neutralization ye-formic acid kunye ne-ammonia. Umkhenkce i-asidi yefom kunye namanzi, phazamisa igesi ye-ammonia ukwenza ixabiso le-pH libe yi-7-7.5, yehlisa iqondo lobushushu ukuya ku -5â kwaye ujikelezise isihluzo ukuyifumana.
2. Kwisisombululo se-asidi ye-90%, dlula i-ammonia gas.
x
3. 100 iinxalenye methyl formate, 100 iinxalenye zamanzi, 0.1 inxalenye formic acid, lungisa pH ukuya 2.5, ubushushu ukuya 70 ° C ngokuvuselela, yongeza 20 iinxalenye zamanzi ammonia, gcina pH 2 ~ 3, emva malunga I-1h, i-70% ye-asidi ye-formic I-methyl ester ifakwe i-hydrolyzed. Kuqhutywa umphunga wangaphakathi. Xa ubushushu bentloko ye-distillation yi-10 ° C, i-methyl formate engaphendulwanga kunye ne-methanol iyachithwa, ishiya isisombululo se-acidic kwi-evaporator. I-ammonia ingathathi hlangothi kwaye uphinde ube ngumphunga ukuze uyifumane ngomxholo we-98%.
