Abstract: A method for preparing an aldehyde including forming a reaction product including an aldehyde by reacting an olefin-based compound with a synthetic gas in a hydroformylation reactor in the presence of a hydroformylation catalyst; introducing the reaction product including the aldehyde to a vaporizer; separating low-boiling point components of the reaction product from an upper part of a vaporizer catch pot included in the vaporizer; separating high-boiling point components of the reaction product from a lower part of the vaporizer catch pot; and recirculating at least a portion of the low-boiling point components separated from an upper part of the vaporizer catch pot back to the vaporizer.

Abstract: Provided are a method, a device, and a computer program for controlling stop of an autonomous vehicle using a speed profile. The method of controlling, by a computing device, stop of an autonomous vehicle using a speed profile includes obtaining surrounding information of an autonomous vehicle, determining candidate routes for controlling stop of the autonomous vehicle on the basis of the surrounding information, calculating scores for candidate driving plans for the autonomous vehicle to travel the determined candidate routes according to a preset speed profile, and finalizing a driving plan for the autonomous vehicle on the basis of the calculated scores.
