Intangiriro
Anhydride ya Valeric ni ifumbire mvaruganda. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya valeric anhydride:
Ubwiza:
- Anhydride ya Valeric ni ibara ritagira ibara, rifite umucyo kandi ufite impumuro nziza.
- Ifata amazi kugirango ivange aside ivanze na valeric anhydride.
Koresha:
- Anhydride ya Valeric ikoreshwa cyane nka reagent kandi hagati muri synthesis.
- Irashobora gukoreshwa mugutegura ibice hamwe nitsinda ryimikorere itandukanye, nka Ethyl acetate, anhydride, na amide.
- Anhydride ya Valeric irashobora kandi gukoreshwa muguhuza imiti yica udukoko n'impumuro nziza.
Uburyo:
- Anhydride ya Valeric isanzwe ikorwa nigisubizo cya aside ya valeric hamwe na anhydride (urugero: anhydride ya acetike).
- Imiterere yimyitwarire irashobora gukorwa mubushyuhe bwicyumba cyangwa gushyuha mukurinda gaze ya inert.
Amakuru yumutekano:
- Anhydride ya Valeric irakaze kandi ikabora, irinde guhura nuruhu n'amaso, kandi urebe neza ko ikorera ahantu hafite umwuka mwiza.
- Mugihe cyo gutunganya no kubika, irinde guhura na okiside cyangwa acide zikomeye hamwe nishingiro kugirango wirinde ingaruka mbi.
- Kurikiza protocole itekanye kumiti yimiti kandi witegure nibikoresho bikingira nka gants ya laboratoire, ibirahure byumutekano, nibindi.
