    摘要: Tertiary alcohols are produced by the hydration of an isoolefin in the presence as catalyst of an acidic cation exchange resin such as a sulfonated styrene-divinylbenzene copolymer, and a polyhydric neo-type alcohol such as neopentyl glycol. The process is useful for separating isobutylene from a hydrocarbon mixture containing its isomers via preparation of the alcohol, separation from the unreacted hydrocarbons and dehydration of the tertiary butyl alcohol to isobutylene.

    摘要: An intruder detection device provides first and second detection areas which are covered by first and second PIR sensors. When intrusion of an object is detected in these areas, the detection signals are amplified by amplifiers, and then processed in a control unit such that orders for generating alarms are output from alarm output units to a monitoring station. While these processed detection signals are output to the alarm output units, the control unit sends other processed signals to LED display units, so that the LED display units turn on alarm lights. The intruder detection device also has a device for separating the object detection areas of the first and second PIR sensors such that their detection areas do not overlap.
