Barqarorlik:

Barqaror. Qochish kerak bo'lgan moddalar orasiga kuchli asoslar, kuchli oksidlovchi moddalar va kukun holidagi metallar, furfuril spirt kiradi. Yonuvchan. Gigroskopik. Mahkam yopilgan butilkalarda bosim to'planishi mumkin, shuning uchun butilkalarni ehtiyotkorlik bilan ochish va vaqti-vaqti bilan shamollatib turish kerak.
