Acetylene is not especially toxic, but when generated from calcium carbide, it can contain toxic impurities such as traces of phosphine and arsine, which give it a distinct garlic-like smell. It is also highly flammable, as are most light hydrocarbons, hence its use in welding.
Sep 24, 2018 · Arne Dedert/Getty Images If you've ever tried to ripen a piece of fruit by sticking it in a bag with a banana, you've harnessed the power of ethylene. Ethylene is an important plant hormone. In
The increase in ethylene follows changes in fruit texture (cell wall material is metabolized into smaller molecular weight units producing a softer texture), composition (generally increase in sugars and decrease in acids) and physiology (pigments - bananas go from green to yellow, and volatile flavor compounds increase in concentration.
Feb 27, 2018 · Ethylene gas can be used to de-green citrus and other crops (e.g., pineapples).

Jan 20, 2021 · Like methane, neither propane nor butane has an odor of its own. However, gas producers add the agent ethyl mercaptan to the gas mixture for safety purposes. This provides a recognizable scent, which will be familiar to anyone who has ever used a gas cylinder BBQ.
Dec 14, 2022 · Fruit ripening patterns of climacteric versus nonclimacteric fruits. (Source: UC Davis). Ethylene is a gaseous plant hormone that plays an important role in inducing the ripening process for many fruits, together with other hormones and signals. An unripe fruit generally has low levels of ethylene.
