Ilactate isetyenziselwa ukugcinwa kokutya, ukufuma kunye nokwandisa incasa
Inkcazo
I-Sodium L-lactate isetyenziselwa ukugcinwa kokutya, ukuthambisa kunye nokuphucula incasa, kunye ne-casin toughening agent kunye ne-agent efunxa amanzi. Ngokuphathelele ukutya kwe-bacteriostasis, i-L-sodium lactate ayinakunqanda kuphela ukuveliswa kweebhaktheriya ezininzi eziphazamisayo, kodwa nazo zinemigangatho eyahlukeneyo yokuthintela kwiibhaktheriya ezininzi ze-pathogenic, ezifana ne-Listeria monocytogenes, i-Salmonella, njl. ISodium L-lactate isetyenziswe ngempumelelo kwiimveliso zenyama ephekiweyo njengenyama ephekiweyo, inyama yenkomo egcadiweyo, ibele lenkukhu, kunye neemveliso zenyama ecoliweyo ezifana nesoseji yenja eshushu, isoseji entsha, isoseji etshisiweyo kunye nesalami.

Isicelo
Isetyenziswa kakhulu ekusetyenzweni nasekuveliseni izinto ze-polylactic acid kunye nokuhlanganiswa kwamachiza e-chiral kunye ne-intermediates ye-pesticide.
Iikhompawundi zeChiral
I-Lactic acid esters isebenzisa i-D-lactic acid njengezinto eziluhlaza zisetyenziswa ngokubanzi kwimveliso yeziqholo, i-synthetic resin coatings, izinto zokuncamathelisa kunye nee-inki zokuprinta, kunye nokucocwa kwemibhobho yepetroleum kunye namashishini e-elektroniki. Phakathi kwabo, i-D-methyl lactate inokuxutywa ngokulinganayo ngamanzi kunye neentlobo ezahlukeneyo ze-polar solvents, i-cellulose acetate, i-cellulose acetobutyrate, njl. kunye neepolymers ezahlukeneyo ze-polar synthetic, kwaye zinendawo yokunyibilika. Sisinyibilikisi esigqwesileyo esinendawo yokubilisa ephezulu ngenxa yoncedo lwaso lobushushu obuphezulu kunye nesantya esicothayo sokumka komphunga. Ingasetyenziselwa njengenxalenye ye-solvent edibeneyo yokuphucula ukusebenza kunye ne-solubilization. Ukongeza, inokuthi isetyenziswe njengento ekrwada kumayeza, izitshabalalisi kunye nezandulela zokwenziwa kwezinye iikhompawundi ze-chiral. , Phakathi.
Izinto ezigqwethekileyo
I-lactic acid yimathiriyeli ekrwada ye-bioplastic polylactic acid (PLA). Iimpawu ezibonakalayo zezinto ze-PLA zixhomekeke ekubunjweni kunye nomxholo we-D kunye ne-L isomers. I-racemate D, i-L-polylactic acid (i-PDLLA) eyenziwe kwi-racemic D, i-L-lactic acid inesakhiwo se-amorphous, kunye neempawu zayo zomatshini zihluphekile, ixesha lokuthotywa lifutshane, kwaye i-shrinkage iyenzeka emzimbeni, kunye nesantya sokunciphisa i-50%. % okanye ngaphezulu, usetyenziso lulinganiselwe. Amacandelo amakhonkco e-L-polylactic acid (PLLA) kunye ne-D-polylactic acid (PDLA) zicwangciswa rhoqo, kwaye i-crystallinity yabo, amandla omatshini kunye nenqanaba lokunyibilika liphezulu kakhulu kune-PDLLA.
