Effect of temperature on the sterilization of isopropyl alcohol by liquid propylene oxide.
Liquid propylene oxide added to a solution of isopropyl alcohol and incubated at different temperatures markedly reduced the time required to sterilize the alcohol solution.
متن کاملPropylene hydration in high-temperature water
The hydration of propylene with sulfuric acid catalyst in high-temperature water was investigated using a flow reaction system. The major product was isopropyl alcohol (IPA). Diisopropyl ether, n-propyl alcohol and C6 olefins were produced as byproducts. The temperature dependency of reaction rate for propylene disappearance was measured in the range of 280-400°C at a fixed pressure of 30 MPa. ...
متن کاملIsopropyl Alcohol Manufacture by the Strong-acid Process
Isopropyl alcohol has been called the first petrochemical (IARC, 1992). It can be prepared via three different methods: indirect hydration of propylene, direct hydration of propylene, and catalytic hydrogenation of acetone. Indirect hydration, also called the sulfuric-acid process, was the only method used to produce isopropanol worldwide until the first commercial direct-hydration process was ...
متن کاملKetoacidosis with unexpected serum isopropyl alcohol.
A 34-year-old woman presented to the emergency department with a chief complaint of acutely worsening abdominal pain. The patient reported the abdominal pain to be in the left lower quadrant and of several months’ duration but noted that it had worsened substantially over the previous 10 days. She also reported diffuse muscle pain and nausea without emesis, no food intake over the previous 72 h...
متن کاملIsopropyl alcohol compared with isopropyl alcohol plus povidone-iodine as skin preparation for prevention of blood culture contamination.
Despite a number of studies on the efficacies of antiseptics for the prevention of blood culture contamination, it still remains unclear which antiseptic should be used. Although the combination of povidone-iodine and isopropyl alcohol has been traditionally used in many institutions, the application of povidone-iodine needs extra time, and there is little evidence that this combination could h...
