A reusable receptacle, and the method of producing the receptacle, for receiving liquid based substances, such as coffee, which rapidly cools the substance to obtain a consumable temperature and which substantially maintains a warm consumable temperature over a sufficient period of time. The receptacle includes a liquid receiving chamber, an interstitial chamber for receiving a phase change material and an interstitial chamber for providing a vacuum insulating chamber. The method of forming the receptacle includes the steps of welding the various wall members to form an integrated thermal mug in an efficient manufacturing process.

The invention provides a high-selectivity protection method of hydroxyl. The method comprises the following steps of: dissolving an organic compound containing two or more hydroxys into proper aprotic solvents; adding an acylation reagent which has the molar weight equal to that of the hydroxy requiring protection; adding anionic salt which is of catalytic amount and is low in price and easy to gain; and reacting for sufficient time at proper temperature, thus protecting one or two hydroxys in a two-hydroxy or multi-hydroxy compound along with high selectivity. The high-selectivity protection method of the hydroxyl has the characteristics of being environment-friendly, mid in reaction condition, simple and convenient in operation and high in yield, and the adopted agents are green, environment-friendly, low in price, easy to gain, high in efficiency, etc.

The invention relates to a control device intelligent collision preventing system based waterproof operating rod controller. The controller comprises an upper cover and a lower housing, wherein a first clamping groove, a second clamping groove, a third clamping groove and a fourth clamping groove are formed in the lower housing from top to bottom; an intelligent collision preventing system is detachably mounted in the second clamping groove; a fourth main control panel containing a plurality of control keys are detachably mounted in the fourth clamping groove; an operating rod control assemblyis detachably mounted on the upper cover. According to the system, the intelligent collision preventing system is arranged; when the time of the motor output end arriving at the set target place is less than the set value, the voltage of the correspondingly controlled motor is reduced, and the rotating speed of the motor is reduced, so that the time of the motor output end arriving at the set target place can be increased, and a user can handle or stop the running of the correspondingly controlled motor with sufficient time, and meanwhile, an alarming device can work to prevent a controlled part from collision; a first-stage waterproof groove, a first-stage waterproof ring, a second-stage waterproof groove and a second-stage waterproof ring are arranged, so that the waterproof effect of the controller can be further improved.
