Best Answer

A good eluent is one that gives good separation between your target compound and impurities. Use a TLC plate to get a feel for the effect of the eluent on your purification. If this is your first time purifying this reaction, a good Rf to aim for in regard to your target compound is 0.2 - 0.25, and impurities should have at least an Rf difference of 0.1 - 0.15 compared to your target compound. Benzene is rather toxic and should not be used for eluting large quantities of compound. But if your reaction is around 2g scale or less, benzene should be ok.

Finding a Good Benzene Lawyer?

Benzene is a harmful drug that has caused a tremendous amount of litigation. This harmful chemical has been found in everything from medications to soda. If a person has consumed Benzene, then he or she may be at risk for some severe medical effects. A person should definitely seek to join in on a class action lawsuit, if he or she has had to have surgery or take medication as a result of Benzene consumption. A lawyer will be able to help recover medical costs that can be given to a person that has consumed Benzene. Benzene consumption is one of the most dangerous things a consumer can engage in these days. When a person consumes Benzene, he or she may suffer from chronic migraines throughout his or her life. In the most severe cases, people have died as a result of consuming Benzene. Some other side effects of Benzene are constant nose bleeding and a feeling of tiredness at all hours of the day. Some people have even been forced to quit their day jobs due to a consumption of Benzene. Many people that consumed Benzene did so in an unintentional way. Many people have not intended to consumer Benzene and knew nothing of its harmful side effects. Only when recent research revealed how dangerous this chemical could be, did lawsuits begin to accumulate against makers of products that contained Benzene. If a person wants to find a good Benzene lawyer, then he or she should see which class action lawsuits already exist against makers of products with Benzene. A person should seek to find a lawyer that is the lead attorney on a large lawsuit against a major producer of products with Benzene. In addition, a person will want to make sure that this lawyer has a thorough understanding of the chemical of Benzene, as well as experience in filing class action lawsuits. The more experience a person has in filing these sorts of lawsuits, the more likely this person is to be successful in a court of law. It is truly a good idea for a person to also hire a lawyer that has a good reputation in the legal community and has never been disbarred. If a lawyer has been disbarred, then the entire Benzene case may be thrown out by the court, which would be a complete waste of a client's time and his or her hard earned money.
