What should be noted when storing Potassium tert-Butoxide

      Potassium tert-Butoxide is a highly alkaline, hygroscopic, and flammable chemical when exposed to water. The key to preservation is strict moisture resistance, oxygen isolation, low temperature, inert protection, and corrosion prevention.

1、 Core Preservation Principles (5 Key Points)

Absolute moisture resistance and isolation from moisture

Highly hygroscopic, rapidly hydrolyzes into KOH and tert butanol upon contact with water, releases heat and flammable gases.

Relative humidity<60%, no water environment throughout the entire process.

Inert gas protection

Solids must be sealed with nitrogen/argon gas to avoid deterioration caused by reactions with O ₂ and CO ₂.

Low temperature and cool

Temperature ≤ 30 ℃, keep away from heat sources and direct sunlight.

Sealed+anti-corrosion container

Use thick glass bottles, fluorine bottles, stainless steel barrels, and strong alkaline corrosive ordinary plastics.

Separate storage and strictly prohibit mixing storage

Stay away from oxidants, acids, water, alcohols, halogenated compounds, etc.

2、 Packaging and sealing requirements

Original factory: Vacuum/nitrogen filled aluminum foil bags, fluorine bottles, sealed steel drums.

Packaging: Dry glass bottle+rubber stopper+aluminum cap, nitrogen filled and pressure sealed; Ordinary rubber plugs/caps cannot be used.

Each time taken: operate quickly, immediately fill with nitrogen and reseal after taking.

3、 Warehouse/environmental conditions

Temperature: ≤ 30 ℃, equipped with air conditioning/temperature control.

Humidity: ≤ 60%, equipped with dehumidifier and hygrometer.

Ventilation: Explosion proof ventilation to avoid the accumulation of flammable gases.

Lighting/Electrical: Explosion proof type.

Ground: corrosion-resistant, easy to clean, anti-seepage.

Area: cool, dry, ventilated, dark, away from water sources.

4、 Key points of daily management

Specially assigned person to lock and label: Strong alkali, flammable, moisture-proof, corrosive.

First in, first out, small portion packaging reduces the number of opening times.

Regular inspection: packaging damage, air leakage, clumping and discoloration.

Weighing, packaging, and opening are prohibited in the storage area.

Weighing: glove box/drying oven/quick operation+nitrogen flow protection.

3、 Safety and Emergency Response

Protection: Alkali resistant gloves, goggles, face shields, anti-static clothing, nitrile gloves.

Leakage: Isolation, dry sand absorption, collection of explosion-proof tools, prohibition of water flushing.

Fire extinguishing: dry powder, carbon dioxide, sand; Do not use water or foam.

First aid: Rinse the skin/eyes with plenty of water for 15 minutes and seek medical attention.
