Acid safety

Reppe s work also resulted in the high pressure route which was estabUshed by BASF at Ludwigshafen in 1956. In this process, acetylene, carbon monoxide, water, and a nickel catalyst react at about 200°C and 13.9 MPa (2016 psi) to give acryUc acid. Safety problems caused by handling of acetylene are alleviated by the use of tetrahydrofuran as an inert solvent. In this process, the catalyst is a mixture of nickel bromide with a cupric bromide promotor. The hquid reactor effluent is degassed and extracted. The acryUc acid is obtained by distillation of the extract and subsequendy esterified to the desked acryhc ester. The BASF process gives acryhc acid, whereas the Rohm and Haas process provides the esters dkecdy.

Sulfuric Acid Safety shower, eyewash fountain, safety goggles, face shield, approved respirator, rubber safety shoes, rubber apron. Observe victim for delayed pulmonary reaction. Wash with large amounts of water. Wash with large amounts of water. Do not use oils or ointments. 

Even air containing email quantifies of brown fumes, if breathed for a long time, produces chronic disease of the respirato. y organs. To prevent such accidents, thorough ventilation in locations where brown fumes are liable to be formed is imperative. In oases of spilling nitric acid, safety is to be sought in retreat from the apartment until the fumes have been replaced by pure air from without.

LAB sulphonic acids are eye and skin irritants. When handling sulphonic acids, safety goggles/face shields, impermeable gloves and a protective apron should be worn. A supply of clean, running water should be available. In case of accidental contact, wash off splashes on the skin using copious supplies of water. With accidental eye contact, wash out the eye with copious supplies of clean water and get medical attention.
