Ifishi y'imiterere:
Icyitegererezo cy'ibicuruzwa ni ubuntu kandi kiraboneka
Izina ry'ubutabire: pirazine
Imvugo zisa: pyrazine
Uburemere bwa molekile: C4H4N2
Ishusho: Ibara ry'umweru kugeza ku muhondo
Gukomera: Irahamye. Irashya cyane. Ntihuye na aside, ibitera ogisijeni.
Ibisobanuro bya pirazine

Ikoreshwa rya pirazine
Pyridazine (290-37-9) ifite atome ebyiri za azote mu mibare 1,2 yitwa pyridazine; Imibare 1,3 yitwa pyrimidines, kandi zombi ni isomer za pyrazines. Pyrazine ni kristu idafite ibara, aho ishonga ni 54 ° C, aho ishyuha ni 115 ~ 116 ° C (768 mm Hg), ubucucike bw'amazi ni 1.0311 (61/4 ° C). Ifite impumuro isa na pyridine. Ishongesha mu mazi, ethanol, ether, nibindi. Pyrazine ni ishingiro rito cyane. Impumuro zayo zisa na pyridine, ntabwo bishoboka cyane ko ihura n'ingaruka za electrophilic substitution reactions, kandi irushaho gukora kuri nucleophiles. Nyuma yuko hydrogen iri kuri atome ya karuboni isimbuwe n'itsinda rya methyl cyangwa halogen, hydrogen iri kuri halogen cyangwa itsinda rya methyl irakora. Pyrazines n'ibikomoka kuri zo bishobora gukorwa hakoreshejwe uburyo butandukanye.
Akamaro ka pirazine
1.Ubuziranenge bwinshi 99.0%min
2. Nta gutoteza amategeko
3. Koresha uburyohe butandukanye
4. Dufite icyemezo cya ISO, dufite icyemezo cya Halal na kosher by'iki gicuruzwa.
5. Dufite ubushobozi bwinshi, bityo, akenshi tugira igihe cyo gutangira vuba.
6. Dushobora gutanga icyitegererezo cya 10g-50g ku buntu ku isuzuma ryawe rya laboratwari.
Gupakira pirazine
1. Ipaki y'icyitegererezo ni 20g/30g/50g kuri buri icupa.
2. Ipaki nto ni 1kg /5kg /10 kg kuri buri icupa.
Ibiro 3.25 kuri buri ngoma
Gupakira bishobora kandi guhindurwa hakurikijwe ibyo abakiriya bakeneye
Ibisabwa mu kubika pirazine:
Komeza upfundike neza, ubibike ahantu hafite umwuka, humutse, kandi hijimye mu bushyuhe busanzwe, ubushyuhe buri munsi ya 20 ℃ buzaba bwiza kurushaho mu gihe bibitswe.
