Used in food flavouring Pentyl butanoate is used in food flavouring Pentyl butyrate, also known as pentyl butanoate or amyl butyrate, is an ester that is formed when pentanol is reacted with butyric acid, usually in the presence of sulfuric acid as a catalyst. Tokyo Chemical Industry Co., Ltd. (TCI) is a leading worldwide manufacturer of specialty organic chemicals founded in 1946. NIST subscription sites provide data under the The objective of the invention is to realize by following method: with butyric acid (content 9798%) and ethanol (content 9293%) is raw material, with sulfuric acid is catalyzer, the bed material proportioning is a butyric acid: ethanol=3.05.0: 1 (mol ratio), and dripping the material proportioning is butyric acid: ethanol=0.851.05: 1 (mol ratio); After treating in the bed material the basic esterification fully of ethanol, will drip and expect to add continuously in the reactor, simultaneously ethyl butyrate and the water form with binary azeotrope be steamed from cat head continuously; The binary azeotrope that steams is after the condensation layering, whole and part lower layer of water of the thick ester of upper strata ethyl butyrate (containing ester amount 9596%) is shifted out the esterification system, and another part of lower layer of water returns cat head as phegma, works to regulate gentle the replenishing in top and forms the required moisture of binary azeotrope; In whole continuous esterification operating process, control reflux rate and discharging speed, make the ethyl butyrate that shifts out the esterification system and the amount of water, substantially equate with the amount that drips the water that material contains in ethyl butyrate that esterification generates and water and ethanol raw material respectively, keep the composition of reactor internal reaction liquid constant substantially, form thus with water band ester, esterification is carried out continuously and stably; The thick ester of ethyl butyrate through light buck wash, after the rectification under vacuum, the ethyl butyrate finished product. Synthesis Reference: Not Available: Material . with date before 31.12.1992 and still valid on 11.12.2001 (patent law change 1993). LOTUS - the natural products occurrence database. 5. thick ester of ethyl butyrate after rectification under vacuum will be washed and the ethyl butyrate chieftain vacuum of last time suck in the 1000 liter rectifying stills, carry out the steam heating vacuum batch distillation.Go out moisture to the greatest extent earlier, go out the ethyl butyrate chieftain again, when fluid is more and stable, fragrance just often, promptly change out finished product over to.

As a solvent and carrier for materials such as nitrocellulose, it was extensively used in the aircraft industry for stiffening and wind-proofing fabric flying surfaces, where it and its derivatives were generally known as 'aircraft dope'. Reduction of odor and nasal pungency associated with aging. Compared to the batch reaction with only 60% conversion of n-butanol, the reactive distillation column can improve the conversion ofn- butanol (up to 93.6%) and the lipase-loaded packing storage in the reaction system at 70 C for 120 days verified that the conversions could still reach 72.5%.
