benzoic acid

benzoic acid

Ikwabizwa ngokuba yi: benzoic acid

Inkcazo: Ifomula yeekhemikhali yi-C6H5COOH, eveliswa yi-oxidation ye-toluene. Isetyenziswa ikakhulu njengesigcini, isibulali ntsholongwane, kwaye ikwasetyenziswa njengendawo yoxubo kunye neekhemikhali eziphakathi.

Isihloko: Chemical noun_izinto ekrwada kunye neemveliso

Amagama ahambelanayo: i-sodium benzoate, i-cholesteryl benzoate, i-preservative yokutya.

I-asidi ye-Benzoic kunye netyuwa yesodium (i-sodium benzoate) zisetyenziswa ngokuqhelekileyo izigcini zokutya. Ineempawu ezinamandla kakhulu ze-antiseptic phantsi kweemeko ze-acidic kwaye zinefuthe lokuthintela ukukhula kwefungi, ibhaktheriya kunye nesikhunta. Xa isetyenziswa njengechiza, i-benzoic acid idla ngokusetyenziswa eluswini zidityaniswe ne-salicylic acid ukunyanga izifo zolusu ezifana nerherho. I-Benzoic acid yinto ekrwada yokuvelisa i-pesticides, idayi, amayeza, iziqholo, i-mordants kunye ne-plasticizers. Ikwayi-modifier ye-polyamide resins kunye ne-alkyd resins kunye ne-rust inhibitor yezixhobo zentsimbi. Ukongeza, i-asidi ye-benzoic inokusetyenziswa kwifayibha yokwenziwa, i-resin, i-coating, irabha kunye nemizi-mveliso yecuba.

I-sodium benzoate ifana ne-potassium sorbate. I-asidi ye-Benzoic kunye netyuwa yesodium yenzeka ngokwemvelo kwizityalo (ingakumbi amajikijolo), kodwa ngokuqhelekileyo ifunyenwe kwimizi-mveliso ngokusebenzisa i-chemical synthesis. I-sodium benzoate inoluhlu olubanzi lwezicelo njengesithinteli kwaye isetyenziswa rhoqo ekutyeni (okufana neviniga, isosi yesoya, inyama, intlanzi, ukutya okufakwe emanzini, njl.njl.), iziselo (ingakumbi iziselo ezithambileyo) kunye neemveliso zokhathalelo lomntu (idayi, izithambiso. , njl.) Amalungiselelo) kunye namanye amashishini, isetyenziswa kakhulu kumazwe ehlabathini lonke.

Ukongeza ekusebenziseni njenge-preservative, i-benzoic acid ikwayindawo ephakathi kwi-organic synthesis. I-Cholesterol benzoate yeyona nto yakudala yesigaba sekristale yolwelo eyafunyanwa ngabantu kwaye yeyona nto iphambili yokubonisa iikristale ezingamanzi. Ingasetyenziswa njengekristale yolwelo lwe-thermochromic emva kokuxutywa ne-cholesterol nonanoate kunye ne-cholesterol oleyl alcohol carbonate, kwaye isetyenziswa kakhulu kwintsimi yokupakisha okuchasene nenkohliso. Ukongeza, i-cholesteryl benzoate ikwayindawo ephakathi kwi-synthesis ye-vitamin D3.

I-Methyl benzoate yenzeka ngokwemvelo kwioli ye-clove, ioli ye-ylang-ylang kunye neoli ye-tuberose. Inevumba elimnandi kwaye isoloko isetyenziswa ekulungiseleleni iziqhumiso kunye nee-oyile eziyimfuneko ezenziweyo. Isenokusetyenziswa njenge-solvent ephilayo. I-Ethyl benzoate yenzeka ngokwendalo kumagqabi ecuba anyangelwe ngumkhuhlane, iipesika, amapayina kunye neti emnyama. Lilungu lencasa yendalo kunye neyokwenziwa kwaye ingasetyenziselwa ukwenza incasa yeziqhamo, njl. njl. Ine nut okanye ivumba elimnandi kwaye isetyenziswa ekutyeni njenge ncasa eyenziweyo. Ikwanazo neempawu ze-antimicrobial kwaye isetyenziselwa ukugcinwa kwizinto zokuthambisa.
