How do you convert 91 percent isopropyl alcohol to 99 percent?
by using fractional distillation
In order for either ethyl or isopropyl alcohol to be considered a general purpose disinfectant it must have what percent alcohol content?
For ethyl alcohol (ethanol) to be considered a general-purpose disinfectant, it typically needs to have an alcohol content of at least 60% to 90%. Isopropyl alcohol (isopropanol) also requires a similar concentration, generally ranging from 70% to 91% alcohol content, to effectively kill a broad range of pathogens. Lower concentrations may not be as effective in achieving disinfection.
What is the density of isopropanol?
The chemical formula of isopropyl alcohol is C3H8O. The density of isopropyl alcohol is 786.00 kilograms per cubic meter.
What are the ingredients in isopropryl rubbing alcohol?
Rubbing alcohol contains two ingredients. One is isopropanol (also called isopropyl alcohol or propan-2-ol), which has C3H7OH as its chemical formula. The other ingredient is water. The rubbing alcohol sold in pharmacies is typically 70% isopropanol by mass and 30% water. It also comes as a 91% isopropanol. The 70% is actually a better disinfectant.Ethyl alcohol is also available as a rubbing alcohol, and is a smaller molecule than isopropanol.Also note that rubbing alcohol that is bought over the counter, especially in the US, is adulterated with all sorts of other molecules, such as benzene and methanol. This is done to keep people from drinking them. (In the US, they are added so that they can be sold without a liquor license.)Read more: What_are_the_ingredients_in_rubbing_alcohol

Does 91 percent isopropyl kill lice on surfaces?
Yes
How fast does 91 isopropyl alcohol evaporate?
Isopropyl alcohol with a concentration of 91 evaporates relatively quickly compared to lower concentrations. The exact rate of evaporation can vary depending on factors such as temperature and air flow.
Is 91 percent Isopropyl Alcohol a better disinfectant than 3 percent Hydrogen Peroxide or is 3 percent Hydrogen Peroxide better?
Hydrogen peroxide 3% is a much better disinfectant. Hydrogen peroxide may be used in the oral cavity for disinfection. Isopropyl alcohol, also known as Rubbing Alcohol is only used on surface skin and not on mucosa. It dries quickly by evaporation, hence it does not have too much contact time to completely disinfect. Hydorgen peroxide's foaming action ensures full coverage of an area, with extended disinfecting action.
What is the density of isopropanol?
The chemical formula of isopropyl alcohol is C3H8O. The density of isopropyl alcohol is 786.00 kilograms per cubic meter.
How do you remove theraputty from fabric?
I used 91% isopropyl alcohol and a rag to remove theraputty from my micro fiber couch cushions. It removed the theraputty easily.
