CAS Number: 590-29-4 Chinese Name: Potassium formate English Name: Potassium formate Alias: Content: 99% Molecular Formula: CHKO? Molecular Weight: 84.11 EINECS Number: 209-677-9 Package: 320 kg/drum Specification: HCOOK content, % ≥96 K?CO? content, % ≤0.5 KOH content, % ≤0.5 KCl content, % ≤1.0 Moisture content, % ≤2.0 Saturated brine density (20°C) g/cm3: 1.55–1.58 Liquid potassium formate content: 74.0% Density (20°C) ≥1.57 g/cm3 pH: Adjustable between 6.5–9.0 according to user requirements Useage: Primarily used in formulating aqueous injection fluids for oil wells. Since the late 1990s, potassium formate has been applied in drilling and completion fluids abroad, especially in high-density systems, with excellent results. Drilling fluid systems prepared with potassium formate offer strong inhibition, good compatibility, environmental protection, and reservoir protection. Field applications show that potassium formate effectively inhibits clay hydration. Physical Properties: The liquid product is a colorless transparent liquid with a saturated solution specific gravity of 1.58 g/cm3. The solid is a white, highly hygroscopic substance with reducibility and can react with strong oxidizers. Its density is 1.9100 g/cm3. It is highly soluble in water, non-toxic, and non-corrosive. Storage and Transportation: This product is a general chemical, non-toxic and harmless. It is highly hygroscopic and should be stored in a dry warehouse. Handle with care to avoid damage to the packaging, which may cause moisture absorption.
