Lub valeric anhydride molecule tuaj yeem pom tias yog tsim los ntawm kev sib txuas ntawm ob pawg valeryl (CH₃(CH₂)₃CO-) ntawm lub atom oxygen. Nws qhov hnyav molecular yog kwv yees li 186.22 g / mol (xws li *n*-valeric anhydride). Nyob rau hauv tus qauv kub thiab siab, valeric anhydride feem ntau tshwm raws li cov kua tsis muaj xim lossis daj daj. Nws muaj qhov ntom ntom ntau dua li cov dej; Nws yog insoluble hauv dej tab sis soluble nyob rau hauv ntau yam organic solvents, xws li ethanol. Nws cov ntsiab lus kub kub yog qhov siab, thiab nws yooj yim rau decomposition thaum distillation ntawm atmospheric siab.
Valeric anhydride yog cov organic compound uas muaj nyob rau hauv chav kawm ntawm carboxylic acid anhydrides. Nws sawv cev rau daim ntawv anhydride ntawm valeric acid (molecular mis: CH₃(CH₂)₃COOH). Acid anhydrides yog cov tebchaw tsim los ntawm lub cev qhuav dej thiab condensation ntawm ob carboxylic acid molecules.
