Toluene is also found in cigarette smoke and car exhaust. If not in contact with air, toluene can remain unchanged in soil or water for a long time. [39] Toluene is a common solvent, e.g. for paints, paint thinners, silicone sealants, [40] many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and ...
A takeover attempt by an individual or a company in which instructions are given to buy all available shares of the target company at current market price as soon as stock exchange is opened for business on a particular date. With this base the bidder makes an attractive offer to the other shareholders in order to make a full takeover bid.
Widow-and-orphan stock: a stock that reliably provides a regular dividend while also yielding a slow but steady rise in market value over the long term. [13] Witching hour: the last hour of stock trading between 3 pm (when the bond market closes) and 4 pm EST (when the stock market closes), which can be characterized by higher-than-average ...
Also called resource cost advantage. The ability of a party (whether an individual, firm, or country) to produce a greater quantity of a good, product, or service than competitors using the same amount of resources. absorption The total demand for all final marketed goods and services by all economic agents resident in an economy, regardless of the origin of the goods and services themselves ...
Toluene is now often used as a substitute for benzene, for instance as a fuel additive. The solvent-properties of the two are similar, but toluene is less toxic and has a wider liquid range. Toluene is also processed into benzene. [69] Major commodity chemicals and polymers derived from benzene. Clicking on the image loads the appropriate article
In the petroleum refining and petrochemical industries, the initialism BTX refers to mixtures of benzene, toluene, and the three xylene isomers, all of which are aromatic hydrocarbons. The xylene isomers are distinguished by the designations ortho – (or o –), meta – (or m –), and para – (or p –) as indicated in the adjacent diagram.
E&P – exploration and production, another name for the upstream sector; EA – exploration asset; EAGE – European Association of Geoscientists and Engineers [11] ECA – Easington Catchment Area; ECD – equivalent circulating density; EDG/EDGE – emergency diesel generator; ECMS – electrical control and monitoring system
Ethyltoluene is produced by ethylation of toluene: CH 3 C 6 H 5 + C 2 H 4 → CH 3 C 6 H 4 C 2 H 5. Over typical acid catalysts, this process gives a mixture of the 2-, 3-, and 4- isomers. Using a modified zeolite catalyst, the alkylation is shape-selective for the 4- isomer. [1] 4-Ethyltoluene is subjected dehydrogenation to give 4 ...
