Alaabta Shiinaha Pgr Xakamaynta Kobaca Dhirta 4 Chlorofenoxyacetic Acid Sodium 4CPA 98%Tc

Baaxadda codsiga

P-chlorophenoxyacetic acid waa xakameynta koritaanka dhirta phenoxyl oo leh firfircoonida auxin.Waxaa inta badan loo isticmaalaa si looga hortago inay soo dhacaan ubaxa iyo miraha, ka joojiso digirta xididada, kor u qaadida dejinta miraha, kicinta midho-free-free, iyo kor u qaadida koritaanka bislaanshaha.

Habka isticmaalka

Si sax ah u miisaan 1 garaam oo sodium chloropenoxate ah, ku rid digsi (ama galaas yar), ku dar qadar yar oo biyo kulul ah ama 95% aalkolo, si joogto ah ugu walaaq ul galaas ilaa ay si buuxda u milanto, ka dibna ku dar biyo 500 ml, taas oo ah, si uu u noqdo 2000 ml/kg oo ah xal kaydka anti-fall.Marka la isticmaalo, waxaa lagu talinayaa in lagu milo qadar go'an oo xal kayd ah oo biyo ah oo loo baahan yahay fiirsashada buufinta, dhuujinta, iwm.
(1) Kahortagga ubaxyada iyo miraha dhacaya:
① Kahor iyo ka dib 9ka subaxnimo, daadi ubax dhedig zucchini furan oo leh 30 ilaa 40 mg/kg oo daawo dareere ah.
②Ku rid 30 ilaa 50 mg/kg oo daawo dareere ah baaquli yar, oo daadi ubaxa subaxda maalinta ubaxa eggplant ( ubaxa dhex geli daawada dareeraha ah, ka dibna taabo caleemaha dhinaca maddiibadda si aad u oggolaato dhibco xad-dhaaf ah ayaa ku qulqulaya baaquli).
③ Iyadoo 1 ilaa 5 mg/kg oo daawo dareere ah, ku buufi inflorescence-ka ubaxa ee digirta, buufi hal mar 10kii maalmoodba mar, buufi laba jeer.
④ Xilliga deyrta ubaxa digirta, oo leh 4 ilaa 5 mg/kg oo daawo dareere ah, buufi ubax, buufi hal mar 4 ilaa 5 maalmood.
⑤Marka 2/3 ubaxyadu ay furmaan inflorescence kasta oo yaanyo ah, ku buufin ubaxa 20 ilaa 30 mg/kg oo daawo dareere ah.

⑥ Xilliga ubaxa ee canabka, ku buufin 25 ilaa 30 mg / kg daawo dareere ah.
⑦ Marka ubaxyada dheddigga qajaarku furmaan, ku buufin ubax 25 ~ 40 mg/kg oo daawo dareere ah.
⑧ 3 maalmood kadib ubaxa basbaaska macaan (kulul), ku buufin ubax 30 ilaa 50 mg/kg oo daawo dareere ah.
⑨ Xilliga ubaxa ee dheddigga cad cad, ku buufin ubaxa 60 ~ 80 mg/kg oo daawo dareere ah.
(2) Kobcinta kaydinta: 3 ilaa 10 maalmood ka hor goosashada kaabajka Shiinaha, dooro galab qorrax leh, oo leh 40 ilaa 100 mg / kg daawo dareere ah, buufin hoosta ka soo jeeda salka kaabajka Shiinaha, caleemaha qoyan iyo daawada dareeraha ah ma daadinayso, waxay yarayn kartaa muddada kaydinta caleen kaabajka Shiinaha.

Arrimaha u baahan feejignaan

(1) Jooji isticmaalka khudaarta 3 maalmood ka hor goosashada.Way ka badbaadsan tahay isticmaalka 2, 4-dhibcood.Isticmaal buufiye yar (sida buufiye dhuunta caafimaadka) si aad ubaxyada ugu buufiso ugana ilaaliso ku buufinta caleemaha iyo caleemaha.Si adag u xakamee qiyaasta, xoogga saarista iyo muddada daawada si aad uga hortagto waxyeelada daroogada.
(2) Ka fogow inaad dawada marsato maalmaha kulul, kulul iyo roobabka si aad uga hortagto waxyeelada daroogada.Ha u isticmaalin wakiilkan khudaarta kaydsan.

Xaaladda kaydinta

Xaaladaha kaydinta 0-6 ° C;Xidh oo bakhaar qallaji.Hawo-qaadista bakhaarka iyo qalajinta heerkulka hooseeya;Kaydi oo si gooni ah uga rari alaabta ceeriin ee cuntada.

Habka diyaarinta

Waxaa lagu helaa uumi phenol iyo chloroacetic acid iyo chlorination.1. Uumiga phenol-ka dhalaalay waxaa lagu qasaa 15% sodium hydroxide xal, iyo chloroacetic acid xal aqueous waxaa lagu dhex milmay sodium carbonate.Labadaba waxaa lagu qasi karaa dheriga falcelinta waxaana lagu kululeeyaa reflux ilaa 4 saac.Ka dib falcelinta, ku dar hydrochloric acid pH ee 2-3, walaaq oo qabow, crystallize, filter, ku dhaq biyaha barafka, qalalan, phenoxyacetic acid ayaa la helay.2. Chlorination Isku qas phenoxyacetic acid iyo glacial acetic acid si ay u milmaan, ku dar kiniiniga iodine, oo ka saar koloriin at 26-34 ℃.Ka dib dhamaadka koloriin, ku rid habeen, maalinta ku xigta biyo qabow crystallization, filter, ku dhaq biyo ilaa dhexdhexaad ah, alaabta la dhammeeyey qalalan.
