O se vaeluaga taua mo le fa'afefeteina o vali.O le vaeluaga fo'i lea ole su'esu'ega o vaila'au fou ubiquitin (X-ray contrast agent);E fa'aaogaina fo'i e fa'apipi'i ai se vaila'au tala fou e fa'avae ile PDE IV inhibitor glycolinic acid;O lo'o fa'aaogaina fo'i e fai ma mea fa'avauvau mo vali fa'asalalau (lanu azo lanumoana).
O le sulfuric acid concentrated (104.3mL, 1.92mol) sa faaopoopo i fagu e tolu, ona faaopoopo lea o le isophthalic acid (40g, 0.24mol), faʻavevesi ma faʻavevela i le 60 ℃, taofi mo le 0.5h, ma le 60% nitric acid (37.8g, 0.36). mol) na faʻaopoopoina e pulea ai le tikeri faʻavavevave.Fa'aopoopo ile 2 itula.A mae'a fa'aopoopo, fa'aola le vevela i le 60 ℃ mo le 2 itula.Fa'alili i lalo ole 50 ° C, ona fa'aopopo lea o le 100mL vai.O mea na faʻamaluluina i le vevela o le potu, sasaa i totonu o le faamama, pamu e aveese le vailaʻau otaota, fufulu le keke faamama i le vai, faʻafefeteina e toe faʻaleleia, ma o le oloa paʻepaʻe e 34.6 kalama, o le fua o le 68.4%.
25kg/ 3-in-1 pepa-palasitika ato tu'ufa'atasi, po'o le taga lalaga, po'o le 25kg/ pakete pepa (φ410x480mm);afifiina e tusa ai ma manaoga o tagata faatau;
Teu i totonu o se atigi pusa malulu i se nofoaga malulu, matutu, lelei le savili e mamao ese mai afi ma mu.
