Usage

General Description

Propyl laurate, also known as propyl dodecanoate, is a chemical compound derived from lauric acid and propanol. It is commonly used as an emollient and skin conditioning agent in various personal care products, such as lotions, creams, and moisturizers. Propyl laurate helps to improve the texture and feel of the skin by creating a smooth, non-greasy film on its surface, while also providing hydration and helping to maintain the skin's natural moisture balance. Additionally, it can act as a fragrance ingredient and solvent in some cosmetic formulations. Overall, propyl laurate is a versatile and multifunctional ingredient that contributes to the sensory and performance attributes of many cosmetic and personal care products.

Tunable aryl imidazolium ionic liquids (TAIILs) as environmentally benign catalysts for the esterification of fatty acids to biodiesel fuel

Herein, we describe the synthesis of tunable aryl imidazolium ionic liquid catalysts and tested for esterification of fatty acids to biodiesel. In this work, six tunable aryl imidazolium ionic liquids (TAIILs) 1a-1f were prepared. These ionic liquids were used as the economical and reusable catalysts for the synthesis of biodiesel fuels. The reaction has been preceded in a monophase at 80 °C for 4 h, after which the product was separated from the catalyst system by a simple liquid/liquid phase separation at room temperature with excellent yields. With the simple post-process, the catalyst is reusable at least 6 times. This novel method offers a short reaction time, good yields, and environmentally benign characteristics.

A Fed-Batch Synthetic Strategy for a Three-Step Enzymatic Synthesis of Poly-?-caprolactone

A three-step enzymatic reaction sequence for the synthesis of poly-?-caprolactone (PCL) was designed running in a fed-batch operation. The first part of the cascade consisted of two oxidation steps starting with alcohol dehydrogenase catalyzed oxidation from cyclohexanol to cyclohexanone and further oxidation to ?-caprolactone (ECL) by means of a Baeyer–Villiger monooxygenase. As a third step, lipase-catalyzed hydrolysis of the lactone to 6-hydroxyhexanoic acid (6-HHA) was designed. With this biocatalytic multistep process reported herein, severe substrate surplus and product inhibition could be circumvented by the fed-batch operation by adding the cyclohexanol substrate and by in situ product removal of ECL by hydrolysis, respectively. Up to 283 mm product concentration of 6-HHA was reached in the fed-batch operated process without loss in productivity within 20 h. After extraction and subsequent polymerization catalyzed by Candida antarctica lipase B, analysis of the unfractionated polymer revealed a bimodal distribution of the polymer population, which reached a mass average molar mass (Mw) value of approximately 63 000 g mol?1 and a dispersity (Mw/Mn) of 1.1 for the higher molecular weight population, which thus revealed an alternative route to the conventional synthesis of PCL.
