WebbThe reaction is not normally done using hydrogen cyanide itself, because this is an extremely poisonous gas. Instead, the aldehyde or ketone is mixed with a solution of … WebbVinyl gloves, which are made from PVC (polyvinyl chloride), are usually the cheapest latex-free gloves. However, many prefer to use higher-end gloves such as nitrile gloves. Nitrile gloves are often preferred since these non-latex gloves best resemble the stretchy feel of latex gloves and are also highly durable and puncture resistant.
