1,4-Dichlorobenzene (1,4-DCB, p-DCB, or para-dichlorobenzene, sometimes abbreviated as PDCB or para) is an aryl chloride and isomer of dichlorobenzene with the formula C 6 H 4 Cl 2. This colorless solid has a strong odor. The molecule consists of a benzene ring with two chlorine atoms (replacing hydrogen atoms) on opposing sites of the ring.
As these products originally contained para-dichlorobenzene (pDCB) they may also be called para blocks. Besides disinfecting, the purpose of these materials is to deodorize restroom urinals. [ 1 ] They are placed above the urinal drain, often in the confines of a small plastic device called a urinal screen that prevents loss down the drain when ...
The latter chemical is also variously labeled as para-dichlorobenzene, p-dichlorobenzene, pDCB, or PDB, making it harder to identify unless all these names and initialisms are known to a potential purchaser. Both of these formulations have the strong, pungent, sickly-sweet odor often associated with mothballs.
Air fresheners from Febreze. Air fresheners are products designed to reduce unwanted odors in indoor spaces, to introduce pleasant fragrances, or both. They typically emit fragrance to mask odors but may use other methods of action such as absorbing, bonding to, or chemically altering compounds in the air that produce smells, killing organisms that produce smells, or disrupting the sense of ...
1,2-Dichlorobenzene, or orthodichlorobenzene (ODCB), is an aryl chloride and isomer of dichlorobenzene with the formula C 6 H 4 Cl 2.This colourless liquid is poorly soluble in water but miscible with most organic solvents.
In the United States, USDA regulations stipulate that AMR machinery cannot grind, crush, or pulverize bones to remove edible meat tissue, and bones must emerge intact. The meat produced in this manner can contain no more than 150(±30) milligrams of calcium per 100 grams product, [5] as calcium in such high concentrations in the product would be indicative of bone being mixed with the meat.
Packet Data Convergence Protocol (PDCP) is specified by 3GPP in TS 25.323 [1] for UMTS, TS 36.323 [2] for LTE and TS 38.323 [3] for 5G.PDCP is located in the Radio Protocol Stack in the UMTS/LTE/5G air interface on top of the RLC layer.
