Isobutylene glycol may be considered a kind of butylene glycol, similarly to butane historically including n-butane and i-butane (isobutane). The modern name for the closely related type of compounds is methylpropanediol. There are two stable structural isomers: 2-methylpropane-1,2-diol; 2-methylpropane-1,3-diol
1,2-Butanediol is a byproduct of the production of 1,4-butanediol from butadiene. [8] It is also a byproduct of the catalytic hydrocracking of starches and sugars such as sorbitol to ethylene glycol and propylene glycol. [9] It can also be obtained from the dihydroxylation of but-1-ene by OsO 4.
1,4-Butanediol, also called Butane-1,4-diol (other names include 1,4-B, BD, BDO and 1,4-BD), [5] is a primary alcohol and an organic compound with the formula HOCH 2 CH 2 CH 2 CH 2 OH. . It is a colorless viscous liquid first synthesized in 1890 via acidic hydrolysis of N,N'-dinitro-1,4-butanediamine by Dutch chemist Pieter Johannes Dekkers, who called it "tetramethylene glyco
Fermentative production of 2,3-butanediol from carbohydrates involves a network of biochemical reactions that can be manipulated to maximize production. [8] 2,3-butanediol has been proposed as a rocket fuel that could be created on Mars by means of cyanobacteria and E. coli, shipped from Earth, working on resources available at the surface of ...
Typically, the live crude from an oil production installation would have a vapor pressure of 120 psia at 100 °F (726 kPa at 37.8 °C) [1] or 125 psig at 60 °F (862 kPa at 15.5 °C). [2] After stabilisation dead crude would have a Reid vapor pressure of 9 – 10 psig at 100 °F (62 – 69 kPa at 37.8 °C).
1,3-Butanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 OH, not to be confused with 1,4 Butanediol. With two alcohol functional groups, the molecule is classified as a diol . The compound without the R (or D) designation is racemic, which is what has been used in most studies before 2023.
De-asphalting the vacuum distillation residue to remove the highest molecular weight alicyclic compounds, which precipitate as black/brown asphaltenes when the mixture is dissolved in C 3 –C 7 alkanes, leaving "de-asphalted oil" (DAO) in solution. A mixture of propane and butane will remove metallic compounds that would interfere with ...
The Mariner East pipelines are a series of Natural Gas Liquids pipelines under construction in the US state of Pennsylvania.The pipelines are intended to facilitate the transfer of Natural Gas Liquids from the Utica Shale and Marcellus Shale Formations to ports on the eastern seaboard where the ethane, butane, pentane, propane mix will be shipped to Scotland for plastics production.
