Vanillin China
Natural Vanillin
Cas No:121-33-5
HS Code: 29124100
Einecs No:204-465-2
MF: C8H8O3
Performance and usages:
Natural vanillin production by biological method. (Streptomyces setonii) in Streptomyces V-1 can use ferulic acid as precursor, biotransformation of vanillin. Application of NaOH solution will prepare ferulic acid mother liquor was added into the V-1 transformation system, we can convert ferulic acid to vanillin efficiency, only by-products less optimization. V-1 medium carbon and nitrogen source system, obtained the highest conversion rate of 66.2%. cell concentration and transformation system of pH has great influence on the transformation effect. Adding adsorption resin can reduce the concentration of reaction solution product of vanillin, reduce the toxic effect on the cell; in fed batch conditions, the final concentration of vanillin the transformation system can reach 1.74%. can be used for biotransformation of isoeugenol to vanillin by another precursor. A strain of Bacillus pumilus (Bacillus pumilus) S-1 can be different The production of eugenol vanillin. By using TLC, GC, LC, GC-MS, LC-MS analysis method and column chromatography and made a lot of analysis on S-1 joined isoeugenol metabolites. The conversion process found in part of isoeugenol monomers into two poly and three innings and enter the degradation pathway; and according to the analysis of products that isoeugenol and a path through the metabolism of vanillin. And may be detected for isoeugenol into the intermediate product of vanillin pathway, speculated it into incense

Claus Catalyst life
Our History
Originally start from activated alumina production from 2009. Till 2010, we found there is a rising demand for alumina desiccant and alumina adsorbent product from oversea countries. After study all the most good quality adsorbent and catalyst from Europe and US carefully, management of Zibo Xiangrun decides to mainly manufacture adsorbent and catalyst type. From 2010, we built pseudo boehmite factory, expanded activated alumina factory, and built an alumina support catalyst factory in Zibo city. In 2015, Shandong Bairui and Zibo Xiangrun combine to a group for adsorbent, catalyst adhesive, gamma activated alumina research and production.
Zibo Xiangrun now is one of the biggest alumina adsorbent in China. Three manufacturing center located in Shandong Province. In 2014, we invest in the largest molecular sieve factory in Henan.

Our Factory
Zibo Xiangrun now is one of the biggest alumina adsorbent in China. Two manufacturing center located in Shandong Province. In 2014, we invest in the largest molecular sieve factory in Henan. Now we have distributors in Australia, South Africa, New Zealand, US, UK, Germany, Frence, Greece, Eygpt, Oman, etc.

Our service
Professional technical proposals:
The specialists of our company can design the technical offer with recommendations of application adsorptive drying systems and purification of gas and-liquid flows.
It usually consists of:
• Designing of adsorption system;
• Calculations of needed quantity of adsorbents ,catalyst and alumina balls ;
• Selection of cycle time ;
• Recommendations on regeneration and cooling of the adsorbent;
• Filling instruction of adsorbents ,catalyst and alumina balls
• Technical guaranties on adsorbent operation.
Catalyst and adsorbent training
Our professional engineer will do the catalyst and adsorbents training as your need. The course mainly include:
lProduction training
lTechnical production points
lMatters needs attention in operation
lCatalyst and adsorbents knowledge training
Regeneration and reactivation of activated alumina:
When activated alumina place a certain time or use some time, and it is no longer effective and must be regenerated. The regeneration temperature is 170-230°C. The actual temperature is set by the design of the unit.
The bed outlet temperature should always be lower than the inlet during heating. If the outlet temperature increase higher than the inlet, so please stop the heating immediately. It indicates that a heat-releasing reaction may be occurring. Close the inlet and outlet valves to the vessel being heated, depressurize it to the flare, and purge it with nitrogen.
During regeneration, the alumina bed may be as hot as 260°C. Always check the temperature in the cooling outlet after regeneration to ensure the bed is cool before exposing it to the feed stream. The adsorbent has high heat capacity and low thermal conductivity. It can stay hot for weeks if a shutdown occurs before the bed has been completely cooled. For systems with automatic switching, always check following a shutdown to ensure that a hot bed is not switched from cooling prematurely.
Advice on bringing installations into operation, and monitoring during operations;
For several years the specialists of our company regularly monitor the performance quality of delivered adsorbents and catalysts. The conditions of running processes, modes of operation, feed composition, regeneration and cooling conditions are thoroughly analyzed. The problems appeared during operation are discussed with the process engineers. The quality of our products is constantly improved.
Professional helpful team and policy sales
lThe customer doesn’t care how much you know until they know how much you care.
lGet closer than ever to your customers. So close that you tell them what they need well before they realize it themselves.
Customer service is not a department, it’s everyone’s Job.Claus Catalyst life
