Acetone can also be produced from isopropanol using several methods, but the main methodis by catalytic dehydrogenation. Production Methods Acetone is obtained by fermentation as a by-product of n-butyl alcohol manufacture, or by chemical synthesis from isopropyl alcohol; from cumene as a by-product...
largest MIBK unit in China was produced by Jinling petrochemical and chemical fertilizer plant in cooperation with Tianjin University by using acetone one-step method in February of 95, and the purity of the product reached 99%. It can also be obtained by condensation of isopropanol at normal ...
Acetone demand has been driven by growing demand for isopropanol (IPA), which has moved into acute shortage over the past three months since one of its uses is in hand sanitizers, a market it shares with ethanol. Demand for hand sanitizers has shot up since the emergence of the COVID-19...
This paper presents a study on the development of a demonstration unit of a isopropanol–acetone–hydrogen chemical heat pump system. All major components in the system were individually investigated, which are endothermic and exothermic reactors and a distillation column. These components were then ...
Under ultraviolet (UV) irradiation(∼254 nm), the acetone/alcohol system produces hydroxyalkylradicals, which are responsible for disulfide bond cleavage in peptides.Acetone/isopropanol is most suitable for optimizing the disulfidereduction products, leading to almost complete conversion in lessthan 5 ...
preparation methodacetone production methods mainly include isopropanol method, cumene method, fermentation method, acetylene hydration method and propylene direct oxidation method. At present, the industrial production of acetone in the world is mainly based on the cumene method. 2/3 of the world's ...
(assigned to LanzaTech) related to expressing multiple copies of acetone and isopropanol biosynthesis gene variants that incorporates discoveries incorporated in this manuscript. M.C.J. and A.S.K. are co-inventors on a US provisional patent application that incorporates discoveries described in this ...
