Magwiridwe ndi Mawonekedwe:

Pharmaceutical intermediates, komanso ntchito yopanga CHIKWANGWANI mankhwala agent.It ntchito mankhwala synthesize theophylline, tiyi kapena khofi ndi nificaran hydrochloride.

Njira Zogwiritsira Ntchito:

(1) mpweya wa methylamine umadutsa mu urea wosungunuka, ndipo mpweya wa ammonia wotulutsidwa umatengedwa ndikubwezeretsedwanso. Pambuyo zomwe mankhwalawo atakhazikika, amachotsedwa ndikusinthidwanso.

(2) mpweya woipa unakonzedwa ndi mpweya-olimba chothandizira anachita ndi monomethylamine.

(3) machitidwe a methyl isocyanate ndi methylamine.

Phukusi ndi Kusunga

Kupaka ndi thumba la 25kg, kapena Sungani mu chidebe choyambirira pamalo ozizira bwino mpweya wabwino. Khalani kutali ndi zosagwirizana. Zotengera zomwe zatsegulidwa ziyenera kusungidwa mosamalakutsekedwanso ndi kusungidwa mowongoka kuti zisatayike. Pewani kusungirako nthawi yayitali.

Zolemba
Zomwe zimagulitsidwa ndizomwe zimangogwiritsidwa ntchito, kufufuza ndi kuzindikiritsa.Sitidzakhala ndi udindo kapena mkangano wa patent.
Ngati muli ndi mafunso paukadaulo kapena kugwiritsa ntchito, chonde titumizireni munthawi yake.
