Se sintetiza fácilmente a partir de sustancias de bajos costes que se consiguen sin ninguna dificultad. El tricloroacetaldehido, obtenido por tratamientos de acetaldehido con cloro, es la materia prima para la obtención del insecticida DDT. Cuando el tricloroacetaldehido se hace raccionar con el clorobenceno en presencia del ácido sulfúrico, el producto es la sustancia clorada DDT bruto. Una vez que la reacción ha terminado y, obtenemos el DDT bruto, se purifica lavándolo con grandes cantidades de agua, haciendo que el DDT se separe de las impurezas junto con el agua, ya que sabemos que al igual que otros hidrocarburos clorados, el DDT es prácticamente insoluble en agua. Tambien podemos lavar el DDT bruto por neutralización con CO3Na2 después de drenar el ácido agotado.
En la siguiente imagen mostramos la formación del DDT en la que participan distintas reacciones de eliminación y protonación.

Bueno esto es lo que he podido encontrar de la sintesis del ddt, espero que lo entendais, en la imagen explica todo.
Gracias.
Perdonad por la tardanza en incluir una nueva entrada en el blog, pero la información que estoy buscando me está costando mucho trabajo. Estoy intentando completar la degradación del ddt buscando en las bases de datos de la Universidad y tengo que traducirlo al español. En cuanto haya terminado os cuelgo todo.
Gracias

Traditional banking has always been a brick and mortar building where you go to deposit or withdraw money.
With the popularity of the Internet and the power it gives people to take control of their lives, many traditional banks have created banking Internet web pages where customers could transfer money, set up bill payments recurring or otherwise, quickly check items that have cleared, and many other functions that can be accessed 24 hours per day 7 days a week.
Since the whole idea of banking Internet is to make banking as easy as possible, most banking Internet sites will allow you to make a transfer from a brick and mortar bank to the banking Internet site as often as you like with no charge or a small fee.
This is amazing and makes traveling a lot less stressful as well because with banking Internet you always know where your account stands.

Historically banks were institutions that held your money under lock and key.
Traditional banks have monitored the popularity and growth of the internet, and realising customers wanted greater control of their affairs, have created their own internet banking web sites.
Others will also enable you to set up online banking by simply transferring your funds by check.

Overall, the majority of people feel that the United States is missing the boat on this matter. Instead of simply regulating the industry like the rest of the countries in the world, they are trying to get rid of it altogether. This may have some benefits, but for the most part there is a chance that it could end up back firing. It will be interesting to see what the Senate decides to do in the upcoming months.
Another important subject I must briefly refer to is "catch-up" staking. If you find that you need to employ this tactic regularly, it means three things: (1) your Selection System sucks, (2) you haven't got a clue about what constitutes a proper Staking Plan, and (3) you have turned your chances of regularly and quickly losing your Base Bank to a 100% certainty!

The relative difficulties of men's and women's fashion
Both men and women may feel the difficulties of maintaining their wardrobe up-to-date and in season, yet men's fashion often feels a lot simpler. Of course, for both genders, clothes and style options can be equally as complicated, and there are lots of'cool'items which can easily become fashion faux pas - who can say they often see people running around in 70s flares? On the other hand, men's fashion includes a few choice goods that will exist forever - which man is planning to look out of position with a good-quality, tailored suit, for instance? Choose traditional cuts, colors and fabrics and you'll never seem out-of-place.
Why common men's fashion is timeless
The common man's suit has hardly changed for over a hundred years. True, there are several versions for different situations, but they are all popular in their quest for a wise, sharp search for the individual. The best part about basic fashion for men is that it's simply fashionable efficiently neat. A well-groomed lady can almost always appear his sharpest in a well-tailored suit, and this is a testament to the design of such clothing. A match will be used to work in many professions due to the professional search it provides to the individual, instilling a feeling of respect and trust. Equally a suit will be utilized to many social functions, such as a tuxedo to a black-tie event. This extraordinary versatility which allows suits to be worn in almost all situations is what gives it its amazing advantage and a permanent invest men's fashion.
Contemporary movements in traditional men's style
Although common men's styles can never be changed, it is interesting to observe that changes in men's fashion trends have produced certain traditional garments back to fashion. The acceptance of vintage clothing, specifically, has brought back a wide-variety of basic styles into men's wardrobes, such as that of the dandy guy. 'Dandy'is a term used to make reference to men who dress in a classic yet lavish way, acting in a polished approach and placing importance on appearance. This development for nearly'over-the-top'traditional fashion for men is apparent from events like the'Tweed Run', where men and women of all ages dress in especially Victorian-style attire and decide to try the roads on vintage cycles - with lots of the men sporting impressive mustaches! This is just one of several types of proof exhibiting the resurrection of such variations. There are also numerous sites on the web which focus on gentlemanly type - such as'The Dandy Project'and'Dandyism'- as well as complete websites such as'The Art of Manliness'focused on providing articles on basic men's fashion and grooming.
In summary, although specific areas of basic men's fashion may be brought back as new styles, the essential outfits which they are derived from will never slip out of fashion.
