This utility model relates to the technical field of pneumatic transmission devices, and discloses a pneumatic transmission device with a temperature control structure. It includes a base, a fan device fixedly mounted on the top of the base, a fan controller fixedly mounted on the front of the fan device, a connecting pipe fixedly connected to the exhaust end of the fan device, and a transmission pipe detachably connected to the right side of the connecting pipe. Through the overall design of the temperature control mechanism, an external temperature transmitter can be attached to the outer wall of the transmission pipe to monitor the temperature of the transmitted material. When the material temperature drops, a small controller will control the heating element to work, heating the transmitted material through the transmission pipe to replenish its heat. When the temperature exceeds a preset value, the small controller will control the heating element to stop working, thus achieving the temperature control function. This avoids the problem of some materials easily deteriorating during transmission, meeting the transmission needs of these materials and improving the applicability of material conveying.

This invention relates to the field of preparation technology of terephthalic acid dicamphor sulfonate organic amine salt, and particularly to a method for synthesizing terephthalic acid dicamphor sulfonate organic amine salt, comprising the following steps: neutralizing camphor sulfonic acid with an organic amine compound in a solvent to generate camphor sulfonate organic amine salt; and condensing camphor sulfonate organic amine salt with terephthalaldehyde under the catalysis of a non-metallic organic alkaline catalyst to obtain terephthalic acid dicamphor sulfonate organic amine salt. The method employs an organic amine neutralization and non-metallic organic alkaline catalytic system, avoiding the introduction of metal ions throughout the process. The product is terephthalic acid dicamphor sulfonate organic amine salt, and no subsequent ion exchange treatment is required, resulting in higher product safety, making it particularly suitable for high-end applications such as sunscreen cosmetics.
