D-LACTIDE Gebruik<\/strong><\/h2>\n

D-(+)-propylester is een cyclische di\u00ebster van melkzuur, een bijproduct dat wordt geproduceerd door spiersarcomeren en rode bloedcellen wanneer het lichaam koolhydraten afbreekt voor energie bij lage zuurstofniveaus. Een geschikte katalysator kan worden gebruikt om de propionylester te polymeriseren tot polymelkzuur, wat resulteert in een materiaal met nuttige eigenschappen.<\/h4>\n

<\/h4>\n

D-LACTIDE Opslag<\/strong><\/h2>\n

1. Deze serie producten zijn biologisch afbreekbare materialen. Vermijd contact met water, zure stoffen, alkalische stoffen, alcoholreagentia en andere reagentia die productdegradatie kunnen veroorzaken tijdens opslag.<\/h4>\n

2. Deze serie producten moet worden verzegeld en tijdens opslag worden bewaard bij een droge en lage temperatuur (koelkast vriezen -20 graden), en moet worden verzegeld met een sealer (de resterende producten mogen na gebruik niet worden verpakt en bewaard in ziplockzakken).<\/h4>\n

3. Wacht tot de temperatuur kamertemperatuur heeft bereikt om het gecondenseerde vocht van het oppervlak van de verpakkingszak af te vegen voordat u de zak opent (het vocht in de lucht zal condenseren op het oppervlak van het product en het product aantasten als het uit de koelkast wordt gehaald zonder constante temperatuur en wordt geopend). De luchtvochtigheid van de omgeving tijdens gebruik moet lager zijn dan 35% om te voorkomen dat de resterende producten vochtig worden en de productkwaliteit aantasten.<\/h4>\n

D-LACTIDE Verpakking<\/strong><\/h2>\n

500g\/zak of 1kg\/zak of 25kg\/trommel.<\/h4>\n

 <\/p>\n

Hoe maak je onderscheid tussen D-LACTIDE en L-LACTIDE?<\/strong><\/h2>\n

1. De naaldvormige kristallen van L- en D-lactide zijn hetzelfde, het smeltpunt is hetzelfde en het uiterlijk is niet te onderscheiden. De racemische vorm kan worden onderscheiden aan de hand van het uiterlijk, is niet naaldvormig en heeft een verschillend smeltpunt.
\n2. Kernmagnetisme en infrarood zijn niet te onderscheiden, optische rotatie wel, linkshandig is negatief, rechtshandig is positief, racemisatie heeft geen optische rotatie<\/h4>\n
