Paragraph 0015; 0033-0038, (2021/03/13)
The invention discloses a preparation method of N-cyclohexyl-2-aminoethanesulfonic acid, which comprises the following steps: heating cyclohexylamine, 1,2-dichloroethane and sodium sulfite to reflux in the presence of a solvent and a catalyst, reacting at reflux temperature, filtering the reaction solution after the reaction is finished, and acidifying and crystallizing the liquid to obtain the N-cyclohexyl-2-aminoethanesulfonic acid. According to the invention, with the cyclohexylamine, 1,2-dichloroethane and sodium sulfite as raw materials, the product can be prepared just through a one-potone-step process; therefore, the reaction conditions are mild, operation is easy, mastering is easy, products obtained after reaction are easy to treat, and the purity of the products is high and canreach 99% or above.

A method for extracting nucleic acids from a biological material such as blood comprises contacting the mixture with a material at a pH such that the material is positively charged and will bind negatively charged nucleic acids and then eluting the nucleic acids at a pH when the said materials possess a neutral or negative charge to release the nucleic acids. The nucleic acids can be removed under mildly alkaline conditions to the maintain integrity of the nucleic acids and to allow retrieval of the nucleic acids in reagents that are immediately compatible with either storage or analytical testing.
