Chemical Process

Acetic acid have formula CH3COOH is known as acid that use in household as additive agent in cooking recipe and more common says with vinegar. Acetic acid is a weak organic acid and the sour constituent of Vinegar. In industry, acetic acid is produced by the destructive distillation of wood and by the catalytic oxidation of formaldehyde. The pure acid is called glacial acetic acid and is a corrosive, colorless liquid with a pungent smell. It solidity at 16.63 o C. Acetic acid reacts with alcohol to form acetates that are widely used as solvents. Acetic acid also react with cellulose to form cellulose acetate, which is the starting material for rayon industry and other artificial fibers and for photographic film. Vinegar in the market can be vary, there are vinegar for sour agent in cooking and also vinegar for fruit ice such as apple vinegar. Vinegar often used as seasoning on food like meat ball and other cooking. apple vinegar white vinegar Other chemicals: Chromi

Chemical Hazard Symbol is regulate by government and International standard to indicate the content of any container that transport that material. The regulation of chemical hazard symbol in Indonesia is made by Ministry of Environment and become update if any changes. Some of symbol of chemical hazard is shown on the picture below. Basic Shape, Size, Materials: The length of the lines making the points should be 1/3 of the height of the diamond and the width of the base should be 1/2 the length of the diamond side. Explosives, Hazardous and Toxic Chemicals Flammable Chemicals: There are two kind of these symbol type, Flammable liquid and Flammable Solid. Symbol of Reactive Hazardous Chemicals: Symbol for Toxic Waste: This is symbol that using International standard, every symbol in the plant should follow the regulation of the above size and dimension already stated by regulation. There are small symbol and big symbol of each chemical characteristic alre

Chemical Process Definition Chemical process is working activity in laboratory, house hold, industry and in many other activity. All incident in a nature also always exist of chemical process, and this chemical process is going on and on. Whithout our knowing it the chemical process in nature is happened. Many reason why the chemical process is happened, this process can happen by automatically or because any other contact or caused by living thing like microorganism. Chemical process happened because of any chemical reaction there, the reaction can be between chemical or reaction caused by the existing of air in atmosphere. Basically there is a contact between them, or make by something else to contact each others. Microorganism can make it contact each others. Chemical process in industry have purpose to produce something and the process of reaction must be controlled. The reaction process should be in certain place and secure, or even should be recondition the environment i

Oxidation Reaction of Chromic Acid For laboratoriest sometimes use chromic acid to clean their glassware after use to prepare chemical reaction or other purpose. The basic on how this acid can clean glass ware is their oxidizing agent to the dirt which stick to the glass. The process of this chromic acid reaction as follows: HCrO 4 -     + 3 Fe ++ + 7 H + --->  Cr +++ + 4 H 2 O 2 HCrO 4 -   + 6 I - + 14 H + --->   2 Cr +++ + 3I 2 + 8H 2 O Chromic acid will oxidized aldehydes to acids and to oxidize secondary alcohol and ketones. Chromic acid also in acetic acid solution can oxidize benzoic acid, ethylbenzene to acetophenone, triphenylmethane to triphenylcarbinol, fluorene to flourene, and chrysese to chrysoquinone. Chromic acid can dissolve in acetic andydride and sulfuric acid, oxidizes o-xylene to be tetra acetated of o-phtalaldehyde. Chromic Acid Prepare Chromic Acid as Cleaning Agent The form of chromic acid can be powder and chromic acid is
