Taw qhia

Nws tuaj yeem txo qhov kub Pheline cov tshuaj tsis txo qhov kub Tollen's reagent. Thaum ntsib ferric chloride, nws yog ntshav mus rau xiav. Soluble hauv ethanol, ether thiab dej kub. Lub precipitated los ntawm cov dej muaj ib tug molecule ntawm crystal dej nrog ib tug melting point ntawm 150-170 ℃, uas hloov raws li lub cua kub ceev thiab decomposes rau hauv resorcinol. Nws yog khaus.

Yav dhau los: Sodium Lauroyl Sarcosinate (CAS # 137-16-6)
