Zachary Walls Evett Hawks Formaldehyde- dangerous or helpful?

Really Awesome Formaldehyde thing ---> [|(awe inspiring)] INTERACTIVENESS!!!**

=Human health implications= 1. Breathing air containing low levels of formaldehyde can cause burning and watering eyes. As levels increase, it can cause burning of the nose and throat, coughing, and difficulty in breathing Large formaldehyde exposures, for example from drinking formaldehyde solutions, are potentially lethal. Formaldehyde is converted to formic acid in the body, leading to a rise in blood acidity, rapid, shallow breathing, hypothermia, and coma or death 2. There’s strong evidence that the human body’s internal chemistry is naturally equipped to process and excrete formaldehyde without harm unless amounts taken in are greater than these protective processes. 3. breathing 4. it can effect the respiratory system 5. if to much gets in it leaks through the processing methods and stays in the body…. I really need help with this one

**Environmental Impact**
Formaldehyde is not very good for the environment it is created from gas and oil. it is made from hydrogen and oxygen. The atmosphere is mostly of formaldehyde about 90%. It is created from cars and busses and also from wood being burned. Formaldehyde decomposes when it is oxidized. Fe2+/H2O2 reaction in which both formaldehyde and methanol were swiftly decomposed. The second and the third stages exerted a somewhat less rapid degradation of both chemicals. The first stage of the oxidation reaction can be discussed by means of the initial average rate and the third stage or Fe3+/H2O2.

**Synthesis/Production Section:**
1-How is the chemical made/refined? 2-How are common products that contain this chemical made? 3-Include at least 3 balanced chemical reactions related to the synthesis of the chemical and/or products. 4-Include a detailed description of the synthesis process.

1a. It is produced principally by the vapour-phase oxidation of methanol

2a. Board designers use computer-aided design systems with special software to layout the circuit pattern on the board. The spaces between electrical conducting paths are often 0.04 inches (1.0 mm) or smaller. The location of the holes for component leads or contact points are also laid out, and this information is translated into instructions for a computer numerical controlled drilling machine or for the automatic solder paster used in the manufacturing process.

2a.For furniture it is used as an inexpensive wood glue

3a. CH3OH→ H2CO+H2 3a.CH3OH → H2CO + H2 3a. 2 CH3OH + O2 → 2 H2CO + 2 H2O 4a. Formaldehyde is produced when methanol is oxidized using a catalyst. The most common catalysts used are a mixture of iron oxide with molybdenum and vanadium or silver metal. In industry and commercial production, the most common method for synthesis is that of FORMOX®. In this method oxygen and methanol react at approximately 250-400 ºC in the presence of iron oxide along with molybdenum or vanadium to produce formaldehyde

**Economic**
has banned it in it’s country but still makes it giving it to the U.S How would I be effected by the ban would probably mean I would have to look for different kinds of shampoo and switch over some house hold items to safer things it would be hassle since I’m not rich and can throw money everywhere. Money would be the crucial part for it. It would bring a lot of up roar for people speaking politically and some countries would rethink they’re possession of the chemical.

**Abstract On Formaldehyde**
Formaldehyde is a naturally produced chemical that can be dangerous in high amounts. It is primarily used in manufacturing and is used for many different products. It is banned within products in California Canada and cannot be sold in China (though can be produced there). It is used mostly in the United States. It is used as a solvent and is used in many organic compounds. Formaldehyde is a low health risk unless someone was to consume a formaldehyde solution or breathe it in high amounts (or breathe in medium amounts for long periods of time). Possible effects of formaldehyde are but not limited too cancer, trouble breathing, and in rare cases loss of life. Formaldehyde is not very good for the environment. It is made from hydrogen and oxygen. Economically formaldehyde is extremely sound. It makes production much easier and much cheaper. Removal of the chemical from production would have noticeable and negative ramifications. Politically. At the moment it is not that big of an issue compared to the other issues are political front has to deal with. Although the chemical is a danger I don’t see much we can do. We can warn everyone more I suppose but removing it would have economic ramifications that we can’t deal with in the current economic crisis. as it stands no action should be taken at this point and time other then a warning and more research on how to render it harmless.



To sum it up Formaldehyde is dangerous but it is a major production chemical. The backlash of removing it would be to great to our frail economy. The only economically sound option we could take is to just spend more on attempting to make formaldehyde safer while keeping it effective.
