Anonymous users2024-02-12I've been in graduate school for two years, and I've been in the lab every day, it's nothing, the windows of the lab are wide open, and if you can react in the fume hood, try to react there, and if your hands are allergic to some reagents, then wear medical gloves.
What do you say Engaging in organic is more or less toxic to the body, but as long as you pay attention, it will definitely not have an effect, look at the academicians of the Chinese Academy of Sciences, a large piece of seventy or eighty organic people.

Anonymous users2024-02-11To engage in organic chemistry is to engage in synthesis (synthesis of new substances).
The most harmful to the human body is to bury organic solvents, and the commonly used organic solvents are: methanol, ethanol, acetonitrile, n-hexane, dichlorosulfoxide, toluene, benzene, xylene, etc. 1Toxicity of organic solvents If people inhale the vapor of organic solvents for a long time, it will cause chronic poisoning, but for a short time.

Anonymous users2024-02-10Lay the foundation to see the "Basic Organic Chemistry" of Xing Qiyi
Then you can watch "New Organic Synthesis" and Wen Ren's "Drug Synthesis Reaction" and so on.
**There are small wood worm forums, zero point gardens, etc.

Both the second and third editions are acceptable. Take a closer look at organic human name reactions and retrosynthetic analysis.

Anonymous users2024-02-07The organic chemistry network also has the Organic Chemistry Forum and the Organic Chemistry Talent Network, as well as the small wood worm at the same time, both of which are relatively professional organic chemistry platforms.

Anonymous users2024-02-06Small woodworms, Haichuan Chemical, Lilac Garden, etc. are all good.

Anonymous users2024-02-05There should also be an organic chemistry talent network, in which there are more technical talents.

Anonymous users2024-02-04Organic Chemistry Network, founded in 2003, is a professional platform for the early organic chemistry industry in China, just like the small woodworm.

Methane and methanol have in common in their molecular composition (both have one carbon atom), and ethanol and acetic acid have in common in their molecular composition (they have two carbon atoms).Similarly, from the above analysis, it can be seen that A and B in the names of such substances are the number of carbon atoms in the molecule of the substance >>>More
At that time, it was very difficult to solve the problem of how the atoms in the molecule of organic compounds were arranged and combined. Originally, organic chemistry used binary theory to solve the structural problem of organic compounds. The dualistic theory holds that the molecules of a compound can be divided into positively charged and negatively charged, and the two are held together by electrostatic force. >>>More
High school is easy to learn, and what we are studying now is organic chemistry, but in college. Organic chemistry in high school is only scratching the surface. In high school, I mainly studied the synthesis of hydrocarbons and their derivatives, and did not involve the difficult part. >>>More
Summary. No, the temperature of the synthesis reaction of organic matter is generally not too high, and too high a temperature may lead to the instability of the reaction products and the slowing down of the reaction rate. >>>More
