The process units of methyl n-nonyl acetaldehyde
Technical field
The present invention relates to compound synthesis device more particularly to the process units of methyl n-nonyl acetaldehyde.
Background technology
Methyl n-nonyl acetaldehyde is mainly used in the head perfume (or spice) of aldehyde perfume (or spice) note, can be used on a small quantity tuberose, cymbidium, honeysuckle flowers, In jasmine, high-grade floral bouquet, perfume type, aldehyde odor type and illusion type essence；It is modern perfume odor type, cigarette perfume type, ambergris, amber Raw material in odor type also micro can be used for food flavor once in a while.Existing process units is mostly more complicated, methyl n-nonyl second Aldehyde reduces by-products content and anticipates with Important Economic as important fragrance, process units quality for improving product quality Justice.
Invention content
The purpose of the present invention is to provide the process units of methyl n-nonyl acetaldehyde, mainly include：Blender (D101) divides Layer device (V101), delivery pump (P101~P103), blender (D102), rectifying column (T101), by flow container (V102), quantizer (V103), rectifying column (T102), rectifying column (T103), by flow container (V104), wherein, the quantizer (V101) is respectively with stirring Mix device (D101), delivery pump (P101) is connected, the blender (D102) respectively with by flow container (V102), quantizer (V103) it is connected, delivery pump (P101) water inlet diameter 170-180mm, blender (D102) outer pot diameter 700-750mm, by Flow container (V104) total volume 1.92-1.95m3。
The process units of methyl n-nonyl acetaldehyde, production procedure are：Methyl nonyl ketone, vinyl chloride ethyl ester, sodium ethoxide are added in In reaction kettle D101, at 30-35 DEG C, 2-3h is reacted.It adds in ice water and continues agitator treating, be then introduced into quantizer V101 and obtain slightly Shrink grease.Through rectifying column T101 Nonyl glycidic acid ethyl ester is obtained in 150-170 DEG C of rectification under vacuum.By Nonyl epoxy Ethyl propionate is imported in reaction kettle D102, is added in sodium hydroxide and is carried out saponification, is controlled and is reacted 1-2h at 40-43 DEG C of temperature, Then it adds in hydrochloric acid and carries out acidification reaction 2-3h.Reaction mass is detached to obtain to Nonyl glycidic acid in quantizer V103, Decarboxylation is distilled through T102 again, most obtains product through T103 rectifications under vacuum afterwards.The invention has the advantages that：Reduce reaction intermediate link, Reaction temperature and reaction time are reduced, improves reaction yield.
