Naphthalene's minimum odor threshold is 0.084 ppm for humans. [42] Mothballs and other products containing naphthalene have been banned within the EU since 2008. [43] [44] In China, the use of naphthalene in mothballs is forbidden. [45] Danger to human health and the common use of natural camphor are cited as reasons for the ban.
Naftalan or Naphtalan is a type of crude oil.It is named after Naftalan, Azerbaijan, where it is found.It is known for its use in alternative medicine.. Naftalan crude oil is too heavy for normal export uses (unlike Azerbaijan's plentiful Caspian Sea oil): it contains about 50 percent cycloalkanes (naphthenic hydrocarbons).
White gas, exemplified by Coleman Camp Fuel, is a common naphtha-based fuel used in many lanterns and stoves.. The word naphtha is from Latin and Ancient Greek (νάφθα), derived from Middle Persian naft ("wet", "naphtha"), [3] [4] the latter meaning of which was an assimilation from the Akkadian napṭu (see Semitic relatives such as Arabic نَفْط nafṭ ["petroleum"], Syriac ...
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.
Naphthalene-2-thiol. Identifiers CAS Number. 91-60-1; 3D model . ... It can be used as a flavouring agent and has been described as having an “artichoke ...
Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil [1] [2] [3] with CAS-no 64742-48-9. [4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or ...
Naphthenic acid can refer to derivatives and isomers of naphthalene carboxylic acids. In the petrochemical industry, NA's refer to alkyl carboxylic acids found in petroleum. [3] The term naphthenic acid has roots in the somewhat archaic term "naphthene" (cycloaliphatic but non-aromatic) used to classify hydrocarbons.
It is a ketone derivative of tetralin, a hydrogenated derivative of naphthalene. History and synthesis
