928-96-1 Usage
Description
Leaf alcohol, also known as cis-3-hexen-1-ol, is a primary alcohol that consists of (3Z)-hex-3-ene substituted by a hydroxy group at position 1. It is a colorless liquid with a characteristic odor of freshly cut grass and green leaves. Leaf alcohol is found in green tea, violet leaf oil, and many types of leaves, herbs, and grasses. It is one of the key volatile constituents of green leaf volatiles (GLV) that can act as an attractant to various insects and is emitted by green plants when they are physically damaged.
Uses
Used in Perfumery:
Leaf alcohol is used as a floral fragrance in perfumery for its characteristic odor of green leaves.
Used in Flavor Industry:
Leaf alcohol is used to obtain natural green top notes in perfumes and flavors, contributing to the fresh, green, and raw fruity taste with a pungent depth.
Used in Synthesis:
Leaf alcohol serves as the starting material for the synthesis of (2E,6Z)-2,6-nonadien-1-ol and (2E,6Z)-2,6-nonadien-1-al, which are important compounds in the flavor and fragrance industry.
Used in Biotechnology:
Biotechnological processes have been developed for the synthesis of leaf alcohol as a natural flavor compound.
Leaf alcohol is also investigated for its antidiabetic activity, indicating potential use in pharmaceutical applications.
Preparation
By the reaction of butyne-1 with ethylene oxide and subsequent selective reduction to the eis isomer (Bedoukian, 1967).
Flammability and Explosibility
Flammable
Synthesis
Extracted from various essential oils and purified by reacting it to the corresponding phthalate or allophanate; it was
synthesized by Ruzi-ka and Schinz, who also clarified its chemical structure; Stoll and Rouve reported on the most significant differences between the natural and the synthetic products (Burdock, 1995)

Check Digit Verification of cas no
The CAS Registry Mumber 928-96-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 928-96:
(5*9)+(4*2)+(3*8)+(2*9)+(1*6)=101
101 % 10 = 1
So 928-96-1 is a valid CAS Registry Number.

Method for synthesizing geraniol from piperylene (by machine translation)
-
Paragraph 0040; 0042-0043, (2020/07/12)
The method comprises the following steps: reacting piperylene with carbon monoxide and hydrogen to prepare an intermediate cis -3 -hexene -1 - aldehyde; and preparing the geraniol through hydrogenation. The yield of the leaf alcohol is 81.56-92 .73percent, the yield of the cis -3 - hexenyl -1 - aldehyde is 80.69-88 .13percent, the yield of the leaf alcohol is -3 - 54.94-80 .35percent (calculated by pentadiene), the yield of the leaf alcohol is 99.2-99 .50percent.1 - percent, and the yield fluctuation range of the leaf alcohol is 10 within 55.53-80 .97percent percent of the yield of the leaf 0.4 alcohol in 98.36-99 .60percent percent.

A facile and straightforward methodology for the preparation of monometallic (copper and palladium) and bimetallic nanocatalysts (NiCu and PdCu) stabilized by a N-heterocyclic carbene ligand is reported. Both colloidal and supported nanoparticles (NPs) on carbon nanotubes (CNTs) were prepared in a one-pot synthesis with outstanding control on their size, morphology and composition. These catalysts were evaluated in the selective hydrogenation of alkynes and alkynols. PdCu/CNTs revealed an efficient catalytic system providing high selectivity in the hydrogenation of terminal and internal alkynes. Moreover, this catalyst was tested in the semi-hydrogenation of acetylene in industrially relevant acetylene/ethylene-rich model gas feeds and showed excellent stability even after 40 h of reaction.
