    Abstract: A method of synthesizing a high purity product of α,α,α′,α′-tetrachloro-p-xylene is disclosed. The method includes carrying out a first stage reaction of terephthaldicarboxaldehyde with a mixture of SOCl2 and dimethylformamide (DMF) to obtain a product mixture containing α,α,α′,α′-tetrachloro-p-xylene as a major product and 4-dichloromethyl benzaldehyde as a side product; adding SOCl2 and DMF to the product mixture of the first stage reaction to undergo a second stage reaction; and to a cool water adding the resulting product mixture from the second stage reaction to obtain a solid product of α,α,α′,α′-tetrachloro-p-xylene with a purity of 90-99 mol %.

    Abstract: A data security protection method generates dynamic encryption keys and dynamic decryption keys for a host and a client during data transmission between the host and the client. The host stores a host initial key K0, and determines a host key Kn using a one-way hash function based on the host initial key K0. The client stores a client initial key K′0, and determines a client key K′n using the one-way hash function based on the client initial key K′0. Original data Rn is encrypted as encrypted data Xn using the host key Kn before being sent to the client. The client decrypts the encrypted data Xn using the client key K′n, to obtain the original data Rn.

    Abstract: A method and a device for purifying 1,4-bis(bromodifluoromethyl)benzene are disclosed. In order to solve the problem of hard to purify and separate 1,4-bis(bromodifluoromethyl)benzene crude products, diphenylmethane that has a higher boiling point and does not interact with 1,4-bis(bromodifluoromethyl)benzene is mixed with the 1,4-bis(bromodifluoromethyl)benzene crude products for evaporation. Afterwards, the purity of the vaporized product is detected and only that reaching an expected purity is collected to obtain high-purity 1,4-bis(bromodifluoromethyl)benzene.
