Naphthalene is a major component of some mothballs.It repels moths as well as some animals. [citation needed]Since mothballs that contain naphthalene are considered hazards, safer alternatives have been developed, such as the use of 1,4-dichlorobenzene, however, 1,4-dichlorobenzene has been declared as a potential neurotoxin. 1,4-dichlorobenzene has been linked to potentially causing ...
8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. [15] As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. It is the main ingredient of traditional mothballs.
Both naphthalene and 1,4-dichlorobenzene undergo sublimation, meaning that they transition from a solid state directly into a gas; this gas is toxic to moths and moth larvae. [1] Due to the health risks of 1,4-dichlorobenzene, and flammability of naphthalene, other substances like camphor are sometimes used.
Urinal deodorizer block. Urinal deodorizer blocks (commonly known as urinal cakes, urinal cookies, urinal biscuits (or jocularly piscuits), urinal donuts, toilet lollies, trough lollies, urinal pucks, hockey pucks, toilet pucks, or urinal peons (alternately urinal pee-ons)) are small disinfectant blocks or tablets that are added to urinals.
Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical (usually gasoline or diesel fuel). The name is a portmanteau of two of the constituents of the original thickening and gelling agents: coprecipitated aluminium salts of na phthenic acid and palm itic acid. [1] A team led by chemist Louis Fieser originally developed ...
Naphtha. Naphtha (/ ˈnæpθə / or / ˈnæfθə /) is a flammable liquid hydrocarbon mixture. Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat. In some industries and regions, the name naphtha refers to crude oil or ...
The horizontal condenser was an extended foul main with the pipe in a zigzag pattern from end to end of one of the retort-house walls. Flange connections were essential as blockages from naphthalene or pitchy deposits were likely to occur. The condensed liquids flowed down the sloping pipes in the same direction as the gas.
Solvent and paint thinner. White Spirit is a petroleum distillate used as a paint thinner and mild solvent. White spirit is an inexpensive petroleum -based replacement for the vegetable -based turpentine. It is commonly used as a paint thinner for oil-based paint and cleaning brushes, and as an organic solvent in other applications.
